Functions Room temperature setpoints 4 4.3 Room temperature setpoints 4.3.1 Description Comfort mode The factory setting for the Comfort basic setpoint is 21 °C and can be changed in the thermostat’s EEPROM via P011, bus with communication object "Comfort basic setpoint" or Siemens smartphone application PCT Go for Android. The last option selected is always used. The Comfort setpoint can be adjusted via the rotary knob, or bus from a remote device like a touch panel, operating unit, and so on.
4 Functions Room temperature setpoints Setpoint limitation For comfort or energy saving purposes, the setpoint setting range can be limited by selecting the most appropriated setpoint concept: ● Setpoint Comfort concept (P010 = 1) for the maximum comfort of the user ● Setpoint energy saving concept (P010 = 2) for energy saving purposes Setpoint comfort concept (P010 = 1) ● ● ● Example Setpoint energy saving concept (P010 = 2) The setpoint limit can be set via P013 (Comfort setpoint minimum) and P016
Functions 4 Room temperature setpoints CAUTION If a setpoint (Economy or Protection) is set to OFF, the thermostat does not control the room temperature in the corresponding mode (heating or cooling). In other words, there is no protective heating or cooling function and thus risk of frost in heating mode or risk of overtemperature in cooling mode! The Economy setpoints (P019, P020) are accessible at the Service level; the Protection setpoints (P100, P101) are accessible at the Expert level. 4.3.

Functions 4 Additional functions The swap function optimizes the use of heating/cooling energy in mixed systems. For example, when the fan coil units are combined with radiant heating/cooling panels, it is more appropriate to start heating with the panels (1st stage heating, YHC1) and start cooling using the fan coil unit (1st stage cooling, YHC2). Enable the swap function by setting P254 (YHC2 output signal, 1st stage in cooling) to ON, depending on the requested control signal.
4 Functions Additional functions these functions are required, the total maximum current on the relay outputs (Q1+Q2+Q3) must not exceed 2 A.
Functions 4 Additional functions To reduce wear and tear on the HVAC equipment, the minimum output On/Off time of the Qx relay output can be adjusted (1…20 minutes) via P212 and P213. The factory setting is 1 minute. When the operating mode is changed from Comfort to Economy or Protection, the relay contact remains energized until the end of the minimum on time set via P212. Note 4.6.
4 Functions Additional functions Note ● ● This function is only active in Comfort mode with: – Valve output type is 3-position (RDG200KN) or DC 0...10 V (RDG260KN) – Electric heater is PWM / 3-position (RDG200KN) or DC 0...10 V (RDG260KN) This function can not be used for radiators.
Functions 4 Additional functions Note When condensation is detected with ● Control only with 6-port control ball valve: o When P201 = 6 or 8, the valve will be close (5 V). o When P201 = 7 or 9, the valve will be close (6 V). ● Control with combi-valve (PICV): The PICV will be closed and the 6-port ball valve will not. The condensation symbol displays during temporary override and the fault "Condensation in room" is sent via bus.

Functions Additional functions Setpoint high Setpoint low 4 The low humidity setpoint (%) is selectable via P026 (setpoint humidity low) and can be adjusted via parameters in Service level or via bus. Setting P026 to OFF (default setting) disables low humidity control. The setting range is limited by P024. S-Mode objects for the humidity setpoint are available when the parameter "Humidity setpoints" is set to as group object in ETS.
4 Functions Additional functions To enable the relay function, set P400 (output Q1), P401 (output Q2) or P402 (output Q3) to 8. The humidification S-Mode object sends ON to the bus as soon as the output is energized. Humidification When the humidity falls below the low setpoint or exceeds the high setpoint, the symbol is displayed and the S-Mode object HumDehumMode sends the HumDehumMode corresponding state on the bus. Max.
Functions Additional functions 4 Note This setting is typically used for cooling applications with fan coil units or split units. When the thermostat is in cooling mode or in the dead zone, the temperature setpoint cooling is shifted only when P461 is less than 0 K. The temperature setpoint heating, if available, remains unchanged. The thermostat guarantees a minimum dead zone between both setpoints. P461 = 0 K When P461 is set to 0 K, the temperature setpoint heating, cooling or both are not shifted.
