Version 3.1.765 August 2019 2 Dry-Matic User Operation System�Benefits� Congratulations on purchasing a Dry-Matic. Your Dry-Matic is designed to provide whole home ventilation 24hrs per day 7 days per week. This provides the benefits of: • Virtually eliminating condensation on windows and cold surfaces by forcing out moist stale air and replacing with relatively dry air. • Reducing airborne concentrations of irritants, asthma causing allergens and smells by forcing out stale air and replacing it with fresh air. • Heat recovery, recycles space heating energy lost to the roof space. • Heat recovery, takes advantage of solar gain to the roof space on those sunny winters’ days.

If the filter timer is activated, the hall controller display will start flashing Dirty Filter to indicate it is time to clean the filters. The white filter bag can be machine washed on gentle cycle or hand washed - vacuum first to remove excess dust. Alternatively replace with a new one. The carbon filter inside the filter box should be replaced every year. You may prefer to get a professional to climb into the attic space to access the filters. Dry-Matic Maintenance Optional Summer Vent Kit The Dry-Matic Summer Ventilation Kit is an optional add-on for Digital Dry-Matics. It can be added during installation or several years after installation. The digital hall controller can be commissioned to control the motorised diverting branch damper, directing air intake from the cooler outside air for summer months. Again, the air intake filter, and the inline ‘Sock’ will need cleaning as above.

Version 3.1.765 August 2019 4 Your Dry-Matic is essentially fully automatic in operation once set up/commissioned to suit your home. The commissioning set up process fine tunes your Dry-Matic in all or some of the following Modes: a. Anti Condensation Mode - when the attic temperature is cooler than the house temperature, the Fan operates at trickle speed to provide background ventilation 24/7. b. Heat Recovery Mode - when attic temperature is warmer than house temperature and house temp is less than “Inside reference temperature” of 20°C*, the fan speed increases to warm the house (speed increases incrementally as the temperature difference between house and attic increases to maximum fan speed at 3°C** difference). c. Heater Mode (heated models only) - if the attic is cold, <15°C** and the house temp is below the reference temp of 20°C*, then the heater can operate to temper the incoming fresh air (heat is proportional to the temperature difference over 3°C**). The heater mode has the following features: c1. A time clock feature (heated models only) accessible from the User Menu, that allows the heater to be turned off / run (as required by thermostat) for programmed hours** (eg. 7pm to 7am), / or continuously, or off. This allows the user to operate the heater overnight, or all the time, or to shut heater down while away for holidays, thereby providing a control of energy usage. c2.To get to User Menu: press and hold mode button†, continue holding while “Entering Menus” appears & hold until “User Setup” shows. Use the up arrow to change the options, Mode button to select. •�Heater enabled Y/N - if N, Heater will not operate •�Heater enabled Y/N - if Y, Options will show next: •�Heater�Continuous - if Y, Heater always enabled •�Heater�Continuous - if N, Heater enabled at night •�Reset Timer Y/N - if Y, Timer & display reset NB. Night operating times can be changed in the ‘Set up Menu” on pp10-13 d. Cool Recovery Mode ** (default: disabled) - when house is hot (above ref temp) and attic temp is less than 20°C* , the fan speed increases (speed is proportional over the temperature difference to 3°C**) to cool the house down. This will not operate if attic temp is below 15°C. e. Auto Summer Shutdown - when house is hot and attic is very hot >27°C**, the system shuts down until the attic temp decreases again. f. Auto Winter Shutdown ** (default: disabled) - If attic temp is less than 2°C**, the system shuts down until attic temp increases again. g. Filter�Timer�- This provides an alarm (flashing display) when fan has operated for 240 days**, indicating that the filter should be cleaned and/or replaced (default: enabled). Can be reset in User Menu (see c2 above).

Version 3.1.765 August 2019 6 It is recommended these units are installed by a preferred installer, please contact us for a list in your area. Installation instructions are a guide only. All electrical connections are subject to NZ law. Pre-Installation checks Before starting the installation, check the site & establish the best position/s of the following components: Diffuser For most small to medium sized homes a single diffuser is usually all that is necessary. It is recommended this be installed into a hallway that is common to most rooms in the home. Installation of the main diffuser into the living / dining area is not recommended. Unit The Unit comprises of the Fan, Heater (if supplied) and Filter box. It is important to install the Unit so that it is as high as possible in the roof space, this is to maximize the benefit of any thermal gain. It also keeps the fan inlet air above dust which may come from the roof insulation. IMPORTANT: The unit must be installed in a perfectly horizontal position to ensure correct heater operation. Attic Controller Is to be installed at the same level as the inlet to the fan, so as to best measure the inlet air condition (temperature) of the unit. The attic controller must be installed vertically, with the pack glands downwards. The attic controller can be fixed to the timber framing in the roof space. Hall Controller Hall controller is to be installed in the house at least 3m from the diffuser but in the same area, approx. 1.5m above the floor. The hall controller should not be installed on an external wall, in a living / dining area or in the immediate vicinity of a heater or heat pump outlet. This is so that the Hall Controller’s built in temperature sensor is not affected by outside air temperature or heating, and should best measure average house temperatures. Ducting Installation of ducting should allow for a full stretch and a smooth sweep onto the rear of the diffuser. This will have a marked effect on the effective operation of the unit air flow & attenuation of fan noise. Installation Procedure Based on the above criteria: 1.�Fit�Diffuser� Before cutting hole for diffuser, check that it will clear ceiling joists and roof structure. Use circle template to cut correct sized hole in the ceiling. Attach duct to grille, taping the centre duct sleeve to the grille spigot then separately taping the insulation/outer to the spigot. Feed ducting through the hole and clip diffuser in place using the spring clips. Ensure grille has a minimum gap of 16mm between inner disk and outer collar.

Version 3.1.765 August 2019 7 2. Assembly of Unit It is suggested that this is done in a clear space on the floor. FAN: Mount fan brackets to side of fan. HEATER (on heated models): Fit to inlet of fan using 4 screws provided (note airflow direction for fan is shown by an arrow on the terminal cover). Ensure airflow direction arrow on heater is the same as direction on fan, ensure heater is mounted so marked top is installed upright. Ensure heater is level. FILTER BOX: Fit to heater (on heated models), or fit to the fan using the supplied collar, so that the hanging bracket is on the heater/fan inlet side. Ensure airflow direction arrow on filter is same as fan. PRE FILTER: Fit white pre filter bag to inlet of filter box. 3. Pre Wiring Using supplied flying leads, connect attic control unit to fan and heater (on heated models). Check wiring diagrams on components carefully. 4. Installing in Attic Lift assembled unit into attic space. Fit supplied cup hooks (x2) to roof structure. Clip supplied bungies (x3) to the three mounting points on assembled unit. Lift unit into position and hook other end of bungy cords over cup hooks. Attach duct to fan outlet, taping core and insulation/outer as before. Adjust length of bungies so unit is level and tighten cable ties to lock unit into position. 5. Mount Attic and Hall Controllers Run supplied cat 5 patch lead to hall controller position (as above), attach to hall controller and attic controller. 6.

Max Fan Speed (default 35%) range 35-60 Provides the ability to adjust fan Hi speed to suit the size of the house. We recommend: 35% for houses up to 150m2 40% for houses up to 200m2 (requires at least a second grille) 45% for houses up to 250m2 (requires at least a second grille) 50% for houses up to 300m2 (requires at least a second grille) For houses larger than this we recommend additional Dry-Matic units. 3. Min Fan Speed (default 25%) range 20-35 Provides the ability to adjust fan minimum speed, we recommend a setting of 25% for this. 4. Fan Speed Heat (default 32%) range 30-45 (option only for heated models) This must be set to ensure that minimum speed is sufficient to ensure heater sail switch operates (with semi dirty filter) and provides sufficient airflow to the number of outlets installed, balanced against too much airflow that will limit temperature rise through the heater. - Adjustment range 30-45% - At default setting, nominal temp rise is 9°C for DM07 - At default setting, nominal temp rise is 18°C for DM15. We recommend Fan Speed Heat set at 30% for this model. - If “heater fault” appears only briefly, this is normal 5. Winter mode Y/N (default Y) - Winter shutdown mode (up button to change to Y, Mode to enter). This setting is available for particularly cold locations, and is mainly when house is not heated (house unoccupied for periods of days or weeks), as in these conditions, when moist outside air is introduced, in some cases it can cause worse air quality, resulting in condensation. If ‘Y’: if attic temp (TA) is less than 0°C (default), the system shuts down until TA increases again. If ‘Y’, next menu is: 5.1 S/down temp? (default 0°C, range: -2° to +2°C ) (up & down arrows to change, mode to enter). 6. Summer-Vent Inst (default N) (up button to change to Y, mode to enter) If ‘Y’ & summer vent kit is installed, the fan can be operated at full speed and the duct diverting damper set to draw air from outside (cool side of the house) for 2, 4, 8, 12, 24hrs or ‘off’, by pressing the up arrow when in operating mode (not in any menu).

Version 3.1.765 August 2019 12 7. Cool Recover Y/N (default N) (up button to change, mode to enter) This mode provides ventilation when house is warm and air is cooler outside. It is manual, as there are times when house has been heated, but is cool outside, hence the limit if the attic temperature is below 15°C. If ‘Y’: When the house (TH) is hot (above the ‘I/side Ref Temp’: TR, default 20°C), and attic temperature (‘O/side Ref Temp’: TA) is less than TR (TATR), the fan speed increases. Fan speed is proportional over the temperature difference to 3°C to cool the house down (the 3°C is changeable using ‘Heat Reco P/band’). This will not operate if attic temp is below 15°C (changeable using ‘O/side Ref Temp’: TA). 8. Filter Timer on (default Y) - Sets a timer to count how many days since last filter change. 9. Filter Alm days (default 240) range 150-240 - Filter Alarm - Display will flash ‘Swap Fltr’ when the filter is due to be changed (see c2 on p4 to reset). 10. I/side Ref Temp - Hall reference temperature TR (default 20°C) - recommend leave set at 20° C 11. O/side Ref Temp - Attic reference temperature TA (default 15°C) - recommend leave set at 15°C 12. O/side Deg offse- Attic Degree Offset (default 0) Provides site calibration of attic temp display if required. eg use -2 if controller reading 2°C too high. 13. I/side Deg Offse- Hall Degree Offset (default 0) Provides site calibration of house display if required. eg use -2 if controller reading 2°C too high. 14. Heat P/band (default 3°) - range 1-7°C. (option only for heated models) At a proportional band of 3°C, heater will start to operate at attic temp 15°C and is fully on when temperature gets down to 12°C. A smaller proportional band will bring heater on over a smaller temperature range. 15. Heat Reco P/band (default 3) - Heat Recovery Proportional Band. - With proportional band of 3°C, the fan starts to speed up when the attic is 1°C warmer than the house. Fan speed is at max when the attic temperature gets to 3°C above house temperature (provided the house is below the reference temperature TR, default 20°C). 16. Cool Reco P/band (default 3) - Cool Recovery Power Band. - With proportional band of 3°C, the fan starts to speed up when the attic is 1°C cooler than the house and is at maximum speed when the attic temperature gets to 3°C below the house temperature (provided house is above the reference temperature TR (default 20°C), cool recovery is enabled and attic is above TA (default 15°C). 17. Summ Temp s/down (default 27°C) range 25-35°C. Auto Summer Shutdown. - When the house is hot and the attic is very hot (TA>27°C), the system shuts down until TA decreases again.
