12 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 fulfilled:
• 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.

13 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-efficiency pump (HE pump)
• PSOL : PWM profile solar pump
• PHEA : PWM profile heating pump
Note
For more information about connecting HE pumps, see page 18.
Minimum speed
In the adjustment channel MIN (2) a relative minimum speed for connected pumps
can be allocated to the outputs R1 and R2.
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) a relative minimum speed for connected pumps
can be allocated to the outputs R1 and R2.
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:
PWM A - Relay 1
PWM B - Relay 2
