Under current operation when a heat pump is power supplied from the mains (i.e. no power breakdown), the UPS THERMOSTAT acts as a connection between the UPS unit (PG500) and the backup battery, ensuring charging. At the same time, it keeps the relay closed, permitting the controller to have the pump under control. When power breakdown occurs, the UPS THERMOSTAT disconnects from the UPS unit (PG500) in order to prevent the battery discharge. If the temperature at the thermostat sensor drops below 5°C, the UPS THERMOSTAT connects the battery with the UPS unit (PG500) and the circulation pump is started. The pump is kept running until the sensor temperature rises above 6°C. This prevents the water circuit of the heat pump from freezing. In this Instruction Manual, the use of a PG500 UPS unit, Z-R230/SO auxiliary relay and a 12V/44Ah backup battery is presumed. 2 Technical data Electric data: Voltage 12 V DC +/- 10 % Electronics consumption (stand-by) 0.08 W Electronics consumption (on) 1.8 W Switching current 30A (no fuse) Power source consumption 0.1 W El. protection IP20, SELV Recommended battery 12 V, 44 Ah capacity Auxiliary relay: Voltage 250 V / 50 Hz Nominal current 20 A Permissible ambient conditions: Operation temperature 0-40 °C Transport/storing temperature 0-60 °C Operation air humidity max. 85 % RH at 25 °C Transport/storing air humidity no moisture condensation permitted Further specifi cations and dimensions: Case two-part ABS plastic Installation position on a wall Overall dimensions 125×75×50 mm Indication LEDs Temperature sensors: Sensor Pt 1000 with 2.5m cable Sensor cable 2×0.75 mm2, max. permissible length 30m

such a manner that the prepared length (2m) of 12V cables (2 blue cables and 2 red ones) will be sufficient. • The sensor shall be placed into a heat pump’s heating water sheath. The sheath shall be mounted into the outdoor pipe section, min. 200mm and no more than 400mm from the wall. Should the 2.5m cable be too short, it may be extended up to 30m (cf. Technical data). 3 UPS THERMOSTAT connections Wiring diagram: 4 UPS THERMOSTAT wall installation Installation Install the UPS THERMOSTAT in dry rooms only. 1. Unscrew the lid screws and remove them. 2. Put the lid aside. Be careful not to damage the electronics inside. 3. Hold the back plate in the desired position and mark 4 mounting holes. Make sure the selected place is fl at and the case will not get distorted after tightening the screws. 4. The enclosed screws and dowels can be used to mount the thermostat on a wall.

All the components shall be wired to the same phase with the same circuit breaker! Procedure for el. wiring: 1. Make sure the the breaker of the circuit in question is switched off . Verify with an electrical tester that the right circuit breaker is off . 2. Plug the cable with wall plug into the socket on the UPS (PG500) back side. Wire the live wire from UPS (L-UPS) to the auxiliary relay, contact No. 3. Then wire the neutral lead N-UPS to the pump N clamp (see the wiring diagram). ATTENTION! The neutral wire from UPS (N-UPS) and the mains neutral wire (N) must not be connected! 3. Connect the heat pump controller outlet designed for a circulation pump to the auxiliary relay, contact No. 1. 4. Wire the live and neutral conductors from the 230V mains to the auxiliary relay contacts A1 and A2. ATTENTION! This shall be the same phase as THERMOSTAT and UPS are wired to. 5. Plug the 230V/12V power supply transformer into one of these two sockets. Then connect the transformer terminal into the socket at the bottom of the UPS THERMOSTAT. The power supply transformer is intended only to check for the presence of the mains. Its power consumption is negligible (cf. Technical data). 6. Wire the UPS THERMOSTAT with UPS (PG500) using the red and blue cables. Marking “UPS+” and “UPS-”. Mind the polarity! 7. Connect the contacts No. 2 and 4 of the auxiliary relay using a jumper and wire them to the live (L) pump clamp. The jumper shall be of the same diameter as the pump L wire. 8. Only after having connected the previously mentioned components, connect the battery to the UPS THERMOSTAT. Marking “UPS+” and “UPS-”. Mind the polarity! 9. As the last step, connect the UPS (the power supply cable is included in its supply) into a 230V/50Hz wall socket. Schéma elektrického zapojení: Wiring diagram: CONTROLLER BATT THERMOSTAT

The sensor shall be placed into a heat pump’s heating water sheath. The sheath shall be mounted into the outdoor pipe section, min. 200 mm and no more than 400 mm from the wall. The sheath shall be located downstream the heat pump – see the layout diagram. If the unit cannot be placed in such a way that the supplied 2.5 m cable is enough, the cable may be extended. The max. permitted sensor cable length is 30 m. The lead cross section is 0.75 sqmm. No contact resistance may be present in the sensor leads. Temperature sensor cable shall be routed separately from mains voltage cables! 7 Description of operation Under current operation (i.e. no power breakdown), the heat pump controller switches the outlet for the circulation pump power supply. The auxiliary relay is wired to this outlet. It is permanently closed as long as electric tension is present in the network. The power supply transformer is connected to the same outlet, being intended just to detect the presence of the mains for the UPS THERMOSTAT. In this situation, the UPS battery is being charged permanently. The pump follows the commands from the controller. The green LEDs on the THERMOSTAT and UPS are lit. During power failure the auxiliary relay contact will switch to power supply from the UPS. Then, these conditions may occur: • If the piping has not cooled down yet, no LEDs are lit on the THERMOSTAT/UPS. • As soon as the outdoor piping cools down below +5°C, the yellow yellow LED is lit on the THERMOSTAT (temperature drop). At the same time, the green LED is lit (circulation pump running). The UPS is power supplied from the battery, the yellow yellow LED is lit. Hot water from the thermal store will warm up the piping and the THERMOSTAT will turn off the circulation pump until the next temperature drop. The piping is being heated for 1-3 minutes (depending on its length and the circulation pump used). • Once the battery is flat, the UPS will not run any more (UPS LED is not lit), and if the piping temperature drops below +5°C, then the yellow yellow and green LEDs are lit. In this case it is recommended to drain water from the outdoor piping. If the frost persisted for a longer time, the heat pump piping and condenser might freeze up. If both the LEDs are lit on the THERMOSTAT and none on the UPS – drain the water!

FAULT DESCRIPTION CAUSE TROUBLESHOOTING Green LED is not lit on the THERMOSTAT but the socket is energized. The 230/12V power supply transformer is not connected. Check the transformer for outgoing voltage and a proper position of the terminal in the unit. The battery is not connected or completely discharged. Check the battery connection, replace the battery. 10. Maintenance Maintenance consists of checking the charging function. Before a heating season starts, check the condition of the battery.
