8.4 Calibration
Calibrate the valve in use to ensure that it opens and closes to the limit positions. This
calibration is automatic.
8.5 Unit jump
The size of one step of each valve position change. This step is performed periodically,
according to the time setting in the Measurement Pause function.
1-20%
8.6 Minimum opening
Set the minimum opening to ensure minimum water flow in the heating system even if
there is no heating requirement (valve temperature is reached). If you want to prevent
water flow into the system if the valve temperature is reached, then set 0%.
0-5%
8.6 Opening time
How long it takes the valve to move from one limit position to another. Close - Open.
Also depends on the type of valve.
120s
8.8 Measurement pause
The pause between valve position changes. The unit measures the valve temperature
and performs the valve position change at the set interval.
30s
8.9 Mixing valve type
Select the type of valve according to the heating system type. The setting will change the
maximum possible temperature of the valve so as not to damage the heating system in
use.
8.9.1 CH valve
Central heating valve. The maximum temperature at the valve should be 85°C.
50-85°C
8.9.2 Underfloor valve
Underfloor valve whose maximum temperature can be 55°C to avoid damage to the
underfloor heating system.
10-55°C
8.10 Equithermal
regulation *
4
Changing the valve temperature according to an outdoor sensor. The temperature at the
valve will be automatically adjusted according to the set values in this function. The
lower the outdoor temperature, the higher the desired valve temperature should be.
Notice: the outdoor sensor must be plugged in, otherwise an error message will occur.
8.10.1 Heating curve
Set the temperatures on the valve according to the outdoor temperature measured by
the outdoor sensor. The temperature at the valve will be automatically adjusted
according to the set values.
Optional
8.11 Room thermostat
Activate the control of the mixing valve with the room thermostat. Valve can respond to
the instruction from the thermostat by lowering/raising valve set temperature, or
closing/opening according to the instruction from the room thermostat.
8.11.1 Regulation without
thermostat
Room thermostat is deactivated. Does not affect the boiler control.
8.11.2 RS reduction
regulator
RT10 room thermostat reduces the temperature at the valve according to the set level in
the Temperature Reduction by Thermostat function.
8.11.3 RS proportional
regulator
RT10 regulator closes or opens the valve according to the current heating demand.
8.11.4 Thermostat
standard
Activates the standard thermostat 1 or 2.
8.11.5 Temperature
reduction by thermostat
Enter the temperature by which the set temperature at the valve will be lowered if the
RS Reduction Controller function has been activated.
8.11.6 Room temperature
difference
Hysteresis of repeated heating command from room thermostat. By how much the room
temperature has to drop to send a command to the room thermostat to start heating.
8.11.7 Change of the set
temperature
If Standard Thermostat 1 or 2 is connected and activated, we can set the temperature at
the valve to drop by a given level when there is no heating instruction from the room
thermostat.
8.12 Proportionality
coefficient
Coefficient for measuring temperatures and updating the heating status. How often the
thermostat checks the temperature and adjusts the valve mode according to the current
situation.
8.13 Opening direction
Change the opening/closing direction of the mixing valve.
8.13.1 Left
The mixing valve moves from right to left when opening.
8.13.2 Right
The mixing valve moves from left to right when opening.
8.14 Selecting CH sensor
Select a sensor that functions as a CH sensor. Linked to the boiler protection function.
