Page 5: App : Sensor Application 1/2
APP : Sensor Application 1/2 This option allows you to choose which sensor is used to control the heating system . If a factory reset is performed, the thermostat will autodetect an external sensor . • A: With this setting, the internal room sensor inside the thermostat controls the heating system . -

APP: Sensor Application 2/2 • AE: With this setting, an optional external room sensor (connected to the floor sensor terminals) controls the heating system . How to execute it: • Access the menu . • Scroll through the menu to APP . •... -
Page 7: Sca : Temperature Scale
SCA : Temperature Scale This option allows you to set the minimum and maximum temperatures to which the thermostat can be set . Operating temperatures: • SChi: Maximum Temperature Scale can be set to between the Minimum Temperature and 40°C . •... -
Page 8: Li : Floor Temperature Limit
Li : Floor Temperature Limit This option allows you to set the minimum and maximum limits for floor temperature . Floor limit temperatures: Floor limit temperatures allow you to set the highest (Lihi) and lowest (LiLo) permissible floor temperature during room temperature control with the sensor application AF . -
Page 9: Tp : Temperature Readout
TP : Temperature Readout Depends on which sensors are connected and which sensor application is chosen . Temperatures from the floor sensor and the internal room sensor can be monitored here . Display settings are not applicable if the sensor applica- tion is set to C . -

LCD : Display Settings This option allows you to select what data you want to be shown in the idle display . SCA = Temperature scale setting: = Celsius (nU = numerical 0-100%) DiS = Displayed in idle display: = Setpoint temperature = Measured temperature Display settings are not applicable if the sensor applica- tion is set to C . -
Page 11: Adj : Adjust
ADJ : Adjust This option allows you to calibrate the measured room temperature . You should calibrate the sensor if the temperature reading differs from the actual temperature . The measured temperature has to be entered . Note that with sensor application F, the temperature is measured in the floor, this temperature would be higher than the ambient temperature . -
Page 12: Nsb : Night Setback
NSB : Night Setback This option allows you to set the value by which the tem- perature should be reduced when NSB is activated . NSB is activated either by the event schedule or with a signal from an external timer connected to terminal S . When the NSB signal is active, a half-moon icon is shown in the display together with the lowered setpoint temperature . -
Page 13: Def : Frost Protection
DEF : Frost Protection This option allows you to set the parameters for any pos- sible frost protection function . An external signal can activate the frost protection, the thermostat will then maintain a fixed floor/room temper- ature . The function is factory-set to 8°C but can be set to values from 5-10°... -
Page 14: Pwm : Pulse Width Modulation
PWM : Pulse Width Modulation With this setting, you can change the duration of the heating periods . Off: Simple “on/off” regulation, where the relay is closed when the measured temperature is below the setpoint, and opened when the measured temperature is above the setpoint . -
Page 15: Pli : Power Limit 1/2
PLI : Power Limit 1/2 This thermostat complies with EN 50559 (VDE 0705-559) for electrical floor heating . The regulation applies to electrical floor heating with a maximum floor weight of 4 kN/m² . To ensure that hotspots due to unintentionally covering up part of the surface are avoided, the heating function can be time-limited as per EN/DIN . -
Page 16: Pli : Power Limit 2/2
PLI : Power Limit 2/2 Equation to calculate number of minutes that could be entered in the PLI menu - when an average heating effect is desired: Average desired heating effect per m ∗ 60 min . Floor heating element effect per m Note! If the result of the equation is negative, then nothing should be entered . -
Page 17: Time : Time And Event Setting 1/2
TIME : Time and Event Setting 1/2 The MTC3 has a timer function that keeps track of the current weekday and time of the day . It is possible to select different event schedules for the MTC3 . The events differ in the number of days that are using 4 events (with a setback period during both night and daytime) and 2 events (only using a setback period for the night) . -
