Switch off - difference:
If this temperature difference is reached, the relay will switch off.
DF-Source
Heat source sensor/heat supplier for differential function
Adjusts the sensor from the heat source.
Diff. Tmin
Minimum temperature on the source sensor for approval of the difference relay.
If the temperature on the source sensor is below this value, the difference function will not be switched on.
Diff.-Drain
Heat decreasing sensor / heat customer for the different functions
Sets the sensor of the heat customer.
Diff. Tmax
Maximum temperature on the target sensor for approval of the difference relay.
If the temperature at the target sensor exceeds this value, the difference function will not be turned on.
Solid fuel boiler
In solid-fuel boiler function, a pump is controlled with a assigned relay, which loads the heat energy from a solid-fuel boiler into a
storage tank.
The solid-fuel boiler function controls the charge pump of a solid-fuel boiler based on the temperature difference between the
solid-fuel boiler sensor and the storage tank sensor.
If a control output (V1 or V2, ...) is used with this function, a speed control with a PWM / 0-10V HE pump is possible.
Solid fuel boiler Tmin
Minimum temperature in the solid fuel boiler to start the pump.
If the temperature at the solid fuel boiler sensor exceeds the temperature set here, the relay switches on the pump, if the other
starting conditions are met.
Below the solids boiler Tmin temperature, the solids boiler function is deactivated.
ΔT Solid fuel boiler
Switch-on and switch-off difference between solid fuel boiler (SFB) and storage tank.
If the temperature difference between the sensors defined for this function exceeds the value set here (ΔT SF On), the function
switches on the assigned output (relay or signal output).
If the set temperature difference (ΔT SF Off) between the solids boiler and the storage tank is below, the function switches off the
assigned output (relay or signal output).
Solid fuel boiler Tmax
Maximum temperature in storage tank. If this is exceeded, the relay is switched off.
Boiler sensor of this function
Sensor used as a solids boiler sensor. Considered for SF Tmin and ΔTon/off.
Storage sensor
Sensor used as a storage tank sensor. Considered for FS Tmax and ΔTon/off.
Error messages
The relay is switched on if one or several of the set protective functions are activated. This function can be inverted so that the
relay is turned on (Duration on) and then turned off again if a protective function is activated.
