If the temperature displayed on the room controller (current temperature on the bottom right of the display) does not match the actual room temperature, the measured temperature of the room sensor can be changed and reset. On calibration, the currently displayed sensor temper- ature needs to be changed to match the directly measured room temperature (reference temper- ature). Note! An incorrectly performed calibration leads to the wrong room temperature measurements and results in incorrect control performance. Use a thermometer with a high degree of accuracy on measuring the reference temperature. How to proceed: Open cover. Select Communication parameter level. Enter the key number. The parameter level is opened. The device address appears on the display. The Baud rate appears on the display. The transmit/receive test appears on the display.

The window contact function depends on the state of binary input BE1:  BE1 = 0: The heating valve is closed. The heating valve is opened for five minutes every 20 minutes  BE1 = 1: Control according to the current operating mode. 3.1.2 Optimization The controller determines the Advance heating time and Cooling down time depending on the building characteristics. The Advance heating time is the time required to achieve the room temperature Set point for time-of-use already when the time-of-use starts. In optimization mode, heating does not start when the time-of-use starts, but at an earlier point in time instead. The Cooling down time is the time required to achieve the room temperature Set point for out- side of time-of-use already when the time-of-use ends. In optimization mode, heating does not finish when the outside of time-of-use starts, but at an earlier point in time instead. Note! Advance heating time and Cooling down time are restricted by the Maximum advance heating time and Maximum cooling down time parameters respectively.

The following applies for outside of time-of-use: When F04 - 0: No cooling When F04 - 1: The temperature is regulated to a raised set point. The setback calculated from the set point for outside of time-of-use during heating is interpreted as an increase. Function WE Configuration Cooling 0 F04* * F04 - 0: No cooling outside of time-of-use F04 - 1: Cooling also outside of time-of-use 3.2.1 Window contact The Window contact function depends on the state of binary input BE1:  BE1 = 0: The cooling valve is closed.  BE1 = 1: Control according to the current operating mode. 3.2.2 Dew point monitoring The dew point monitoring uses the binary input BE2:  BE2 = 0: Temperature regulated to Set point for outside of time-of-use.  BE2 = 1: Cooling is interrupted. Function WE Configuration Function BE2 0 F01 - 1 EB 5572 EN 17 Functions

The adjusted operating mode override is processed by binary input BE2:  BE2 = 0: Control according to the current operating mode.  BE2 = 1: The temperature is regulated to Set point for time-of-use regardless of the programmed time schedule or operating mode. Note! If the vacation mode is set, the setting F01 - 1 has no function; the controller continues to regu- late the temperature to Set point for vacation mode.

Note! Changes to the control signal that are smaller than the value set in Min. control signal parameter are not processed. Parameter WE Parameter level / Range of values Min. control signal 5 % PA Control / 1 to 100 % Three-point stepping output (heating only) The control loop functions with a PI control algorithm. The heating valve reacts to pulses which the controller issues when a system deviation exists. In particular, the length of the first pulse de- pends on the size of the system deviation and the selected Gain KP (the pulse length increases as KP rises). Pulse length and interval time change continuously until the system deviation is eliminated. The interval between pulses is influenced considerably by the Reset time TN (the in- terval increases as TN rises). The Valve transit time TY indicates how long the valve needs to move through the range from 0 to 100 %. Parameters WE Parameter level / Range of values Switching outputs function 1 PA Control / Select: 1 Gain KP 1.0 PA Control / 0.1 to 100 Reset time TN 180 s PA Control / 0 to 1000 s Valve transit time TY1 45 s PA Control / 0 to 1000 s 2 x On/off PPM (heating and cooling) The control signals applied at the 0 to 10 V output that exceed the value entered in the Minimum control signal parameter, are issued as a pulse width modulated signal with the basic frequency 1/TY1 (heating) or 1/TY2 (cooling).

The output signal (AA1 heating, AA2 cooling) of the controller is switched on or off. A control signal is issued when the temperature exceeds or falls below the set point, depending on the controlled variable. If the control signal exceeds the Min. Control signal, the on-off ther- mostat is switched on or off. Parameter WE Parameter level / Range of values Switching outputs function 1 PA Control / Select: 3 Triac 1 and triac 2 switched according to the time schedule Both triacs are switched on together depending on the time schedule or the adjusted operating mode. Both triacs are closed outside of time-of-use.

Triac 2 switches on when the control signal for cooling = 100 % and when a system deviation (cooling demand) continues to exist. Triac 2 functions in sequence to the control signal for cool- ing, for example, to connect additional cooling equipment. When the temperature reaches the set point, triac 2 switches off again.

cate with a control system (GLT). A complete control system can be implemented using a suit- able software to visualize the process and to enable communication. The operation of the controller requires a constant bus link (data cable). The bus line is designed in an open ring structure to connect individual control equipment. The data cable is connected at the end of the bus line to the control station over a RS-485/RS-232 converter (e.g. CoRe 01). The bus connection range (cable length) is maximum 1200 m. A maximum of 128 devices can be connected in such a segment. Repeaters must be used (for example, CoRe 01) to regenerate the signal level over long distances or when more than 32 devices are connected to one bus line. A maximum of 246 devices can be addressed and connected to a bus with 8-bit addressing. Caution! You are required to follow the relevant standards and regulations applicable to light- ning and overvoltage protection on installing the controller. A transmitting and/or receiving test can be initiated in the Communication parameter level:  RC blinking : Receiving data telegrams from control station (GLT), on the display even when they are intended for other controllers  : Controller transmitting to control station (GLT) Description of the parameters that need to be set: The Device address is used to identify the controller. An address may only be assigned once within a system. The Baud rate indicates the transfer rate between control system and controller in a bus system.
