Transfer of the boiler temperature to modulating external boilers
You can transfer the required boiler temperature to a mod-
ulating external boiler as a voltage signal with functions
28 and 29 using Output A15.
In the "Outputs" menu, Output A15 must be set with the
appropriate scaling.

Explanation
Compares the inflow (pre-run) temperature in the primary circuit "T.Solar Pre1" (sensor S16
or RF2) with the storage tank reference temperature "T.Ref.Sto" (sensor S3 or T4) to enable
the solar pump in the secondary circuit ("Solar Pump2").
"Solar Pump2" switches on, if:
- "Solar Pump1" is on and "T.Solar Pre1" > "T.Ref.Sto" + 10K
"Psolar Pump2" switches off, if:
- "Solar Pump1" is off or "T.Solar Pre1" < "T.Ref.Sto" + 7K
Controls the speed of the solar pump "Solar Pump2" in the secondary circuit: The speed of
the pump is controlled so that "T.Solar Pre2" is 5 Kelvin below that of "T.Solar Pre1".
Status request for heating and WW request.
Determines each of the important target temperatures (nom. temperatures) using the func-
tions "MAX(AN)" and "WW_REQ".
No. Output
"Solar Pump1"/Psolar
A1 The speed of the solar pump in the primary circuit
is controlled in the "AUTO" setting.
"Solar Pump2"/Opt.2
A7 The speed of the solar pump in the secondary cir-
cuit is controlled in the "AUTO" setting.
Standard settings for scaling:
150 scale division (= 15 °C) is supplied with 0.6V and
900 scale division (= 90 °C) is supplied with 10.0V.
You can only change the scaling in the "Expert" operating
mode.
