Page 12: Parameter Window "Temperature Regulation Configuration
4.2 Parameter Window “Temperature Regulation Configuration” Parameters concerning the regulation algorithm and the type of HVAC plant system and the fancoil type are configured here. This parameter window also provides the temperature adjustment for the temperature sensor calibration (± 1,5° C) and the hysteresis regulation range for the two step setpoint control (ON/OFF). - Page 13 The P control is normally used in: i. plants where temperature doesn’t change frequently and rapidly. ii. plants where a constant deviation between the temperature and the setpoint is acceptable (within a certain limited range) iii. plants with great volumes (accumulators) or with constant flow rate. Option “Integral Band”: the integral action acts on the actuator with a speed proportional to the deviation between the temperature and the setpoint.
- Page 14 object (“Valve 0=Cold / 1 = Warm”) in order to open or close the valve connected to an actuator. Option “4 Tubes Circuit ON/OFF”: with this option the HVAC plan is composed of 4 circuits with ON/OFF switching Cold and Warm valves. The thermostat provides two 1 bit object, one dedicated to control the Warm valve and the other to Cold valve via an external bus actuator.
- Page 15 Temperature Coefficient Regulation Options: ±0,1° C….±0,3…..±1,0° C With this parameter is possible to select a level for the hysteresis (±∆T) by which the setpoint fluctuates. The HVAC plant is switched ON in case of an ON/OFF control when temperature falls outside the hysteresis (see next fig. 4). The hysteresis is based on how quickly the heating system can warm up the room or how quickly the cooling system can lower the temperature in the room as well as the customer’s sensitivity to temperature levels.

Page 16: Parameter Window "Setpoint Configuration
4.3 Parameter Window “Setpoint Configuration” This window allows parameter settings for all setpoints associated to every mode (Comfort, Standby, Economy) and also for Heating (Winter) and Cooling (Summer) operation. The setpoint values can be modified also via bus in run time by a centralized unit (e.g. - Page 17 Setpoint Standby Summer Options: +5° C….+26° C…..+45° C Standby mode setpoint in Summer (Cooling) Setpoint Economy Winter Options: +5° C….+15° C…..+45° C Economy mode setpoint in Winter (Heating) Setpoint Economy Summer Options: +5° C….+30° C…..+45° C Economy mode setpoint in Summer (Cooling) Next figure shows the setpoints settings in Summer/Winter (Heating/Cooling) mode.
- Page 18 Setpoint Antifreeze Winter Options: +4° C….+7° C…..+10° C Setpoint for frost protection (in Winter/Heating mode). The frost protection is activated via bus with the 1 bit object “Antifreeze” or in case the function “Window Switch” is associated to the binary input available. If a window is opened and this status is detected through the binary input channel interfaced with a window contact so the HVAC system is switched OFF immediately.

4.4 Parameter Window “Input Configuration” This window allows setting parameters for binary input operating functions. Fig. 7: Parameter window for “Input Configuration” with Function = “Windows Switch” and “Cyclic Send” = “ON” settings. Function This parameter allows setting of function associated to the binary input channel as “Window Switch”... - Page 20 If the input is associated to “Windows Switch” function the following parameters are visible and enabled. Windows Switch Mode This parameter allows the input contact usage setting if normally opened or closed. Options: Normally Open Normally Close Option “Normally Open”: Window Close = contact open Window Open = contact closed.
- Page 21 Mode This parameter determines which switching values is written into the memory location of the communication object when the signal state changes at the input. A rising edge is when the signal state at the input changes from logic “0” to “1” while a falling edge is a change from logic “1”...

The two parameters next remain the same as explained before (in this case the cyclical sending is concerned the 1 bit object “Digital Input”). Cyclic Send Options: This parameter enable the cyclical sending of current value of the binary Input to the bus at a set interval with the object “Digital Input”. - Page 23 Function Options: Velocity V1 Fancoil General Purpose Option “Velocity V1 Fancoil”: the output relay can be used to control the velocity V1 of a fan coil in case a fan coil is used. The type of fan coil can be selected with the parameter “Fancoil Type” in the “Temperature Regulation Configuration”...
- Page 24 Mode Option: Normal Timing Option “On-Off” : the output relay will be switched ON by sending an ON command and will be switched OFF buy sending an OFF command within the associated object “Relay OnBoard”. The status of the relay contact is inverted by the parameter setting “Contact”= “Normally Close”.

5 Communication Objects EIB/KNX communication objects provided within application program “EEL_RTH1_10 Room Thermostat” are the following: Fig. 11:Communication Objects EIB/KNX provided with the application program (NB: some objects are visible only if enabled by specific parameter setting).). Funzione Nome Tipo Flag On/Off 0=Standby / 1=Comfort... - Page 26 The fixed temperature Set point is used when passing from Winter mode to Summer mode and vice versa. Note: the thermostat TM11A01KNX (TM11A11KNX) doesn’t toggle automatically between Summer (Cooling) and Winter (Heating) mode but only by receiving this object from the bus.
