USER PARAMETERS DETAILS
Below, there is a detailed explanation on each single “User parameter”.
“AFr PAr 1.0” ANTI-FREEZE SETTING
The Anti-freeze mode allows you to select a minimum temperature to be maintained when the programmable thermostat is off, so as to protect both
the room and the equipment when the room temperature falls below the set value.
The parameter can be set in the range OFF, 0,5°C .. 25°C. It is possible to deactivate the anti-freeze operation setting it to the minimum until the
writing “OFF” is displayed.
The device leaves the factory with the Anti-freeze mode set on +6°C.
WARNING
The mode is active only when the device has been set on heating mode.
“OFS1 PAr 2.0” INTERNAL SENSOR OFFSET SETTING
With this parameter it is possible to correct the temperature reading of the internal sensor by ±10°C, in order to correct any systematic reading errors
due to the positioning of the programmable thermostat in areas unsuitable for measuring room temperature.
The device leaves the factory with the Offset set to 0.0°C.
“OFS2 PAr 3.0” REMOTE SENSOR OFFSET SETTING
With this parameter it is possible to correct the temperature reading of the remote sensor by ±10°C, in order to correct any systematic reading errors
due to the positioning of the remote sensor in areas unsuitable for measuring the room temperature.
The device leaves the factory with the Offset set to 0.0°C.
“rEG PAr 4.0” REGULATION SENSOR CHOICE SETTING
This parameter sets whether the room temperature regulation is made based on the programmable thermostat internal sensor or the remote sensor,
wired at terminals 4 and 5.
“Int”: internal sensor
“EHt”: remote sensor
“HYSt PAr 5.0” DIFFERENTIAL SETTING (Hysteresis)
This parameter sets the hysteresis, in °C, used in the temperature regulation.
The parameter can be set in the range 0,0°C .. 5°C. The device leaves the factory with the hysteresis set to 0,2°C.

“H_C PAr 6.0” SETTING HEATING / COOLING
This setting allows to invert the relay operation logic depending whether a cooling or heating system is being used.
The parameter can be set between:
“HEAt”: Heating
“COOL”: Cooling
The programmable thermostat leaves the factory set on heating mode.
“tPI PAr 7.0” PWM OUTPUT REGULATION
Allows to choose whether the relay output must be ON/OFF driven or PWM (Pulse Width Modulation) driven.
With ON/OFF regulation (parameter set to no) the programmable thermostat will regulate the output with customizable hysteresis on parameter
“HYSt“, while with PWM regulation (parameter set to YES) there will be a proportional adjustment which is possible to adapt to different environments
with the parameters “bP” (proportional band), “t int“ (integrative time), “PCYC“ (PWM time cycle), “PMIn” (minimum ON time of the PWM).
The device leaves the factory with parameter set to no.
The following parameters will be displayed only if the “tPI“ parameter has been set to “YES”.
“bP PAr 7.1” PWM PROPORTIONAL BAND
This parameter allows to customize the proportional band in the range 1.0°C .. +8.0°C.
The device leaves the factory with parameter set to +2°C.
“t Int PAr 7.2” INTEGRATIVE TIME
This parameter allows to customize the integral time of the proportional regulation in the range OFF / 5 .. 180 minutes, by 5 minutes steps.
When set to OFF, no integral action will be done.
The device leaves the factory with parameter set on OFF.
“PCYC PAr 7.3” PWM CYCLE TIME
This parameter denes the duration of each PWM cycle in minutes, i.e. every how many minutes is the variable width pulse repeated.
The parameter can be set in the range 15 .. 60 minutes.
The device leaves the factory with parameter set on 30 minutes.
“PMIn PAr 7.4” MINIMUM TIME PWM ON
This parameter denes the minimum PWM pulse width i.e. the minimum output switch-on time.
When an electro-thermal actuator is wired to the output, this parameter must be set with the actuator’s travel time, otherwise ‘on’ pulses of a lower
