Return preheating
The return preheating function can be used for transferring heat from a heat source
to the heating circuit return.
The relay (system-dependent) is energised when both switch-on conditions are fullled:
• the temperature difference between the sensors store return and heating circuit
return has exceeded the switch-on temperature difference.
• the temperature at the heating circuit return has exceeded the minimum temperature.
The switch-on hysteresis is -5 K.

Relay control
With this parameter, the relay control type can be adjusted. The following types
can be selected:
Adjustment for standard pump without speed control
• OnOF : Pump on / pump off
Adjustment for standard pump with speed control
• PULS : Burst control via semiconductor relay
Adjustment for high-efciency pump (HE pump)
• PSOL : PWM prole solar pump
• PHEA : PWM prole heating pump
• 0-10 : Speed control via 0 - 10 V signal
• ADAP : Speed control signal via a VBus

/ PWM interface adapter
Note:
For more information about connecting HE pumps, see page 36.
Minimum speed
In the adjustment channel MIN(2, 3) a relative minimum speed for connected
pumps can be allocated to the outputs R1, R2 and R3.
Note:
When loads which are not speed-controlled (e. g. valves) are used, the pump
speed value of the corresponding relay must be set to 100 % or the control
type must be set to ONOF in order to deactivate pump speed control.
Maximum speed
In the adjustment channel MAX(2, 3) a relative minimum speed for connected
pumps can be allocated to the outputs R1, R2 and R3.
Note:
When loads which are not speed-controlled (e. g. valves) are used, the pump
speed value of the corresponding relay must be set to 100 % or the control
type must be set to ONOF in order to deactivate pump speed control.
Relay allocation for PWM outputs
A relay can be allocated to the PWM outputs PWMA and PWMB in the
PWMA(B) channel.
