3
Speed of heating circuit pump Q2
Output Ux is assigned to the heating circuit pump.
4
Reserved
With the present line of controllers, this setting has no function.
5
Heat source temperature setpoint (general)
Output Ux is used for delivering a voltage-proportional demand for heat (DC 0…10
V) (refer to operating line 891).
Heat source releases (operating lines 630 through 632) are not taken into account.
Green button and heat generation lock (operating lines 376 and 473) continue to
be active.
6
Temperature setpoint heat pump
Output Ux is used for delivering a voltage-proportional demand for heat (DC 0…10
V) (refer to operating line 891).
The heat demand is delivered only if the heat pump is released (according to the
“Lead heat source”, operating line 620, and “Release of heat pump above the out-
side temperature threshold”, operating line 631).
Green button and heat generation lock (operating lines 376 and 473) continue to
be active.
7
Temperature setpoint oil- / gas-fired boiler
Output Ux is used for delivering a voltage-proportional demand for heat (DC 0…10
V) (refer to operating line 891).
The heat demand is delivered only if the oil- / gas-fired boiler is released (accord-
ing to “Lead heat source”, operating line 620, and “Release of oil- / gas-fired boiler
below the outside temperature threshold”, operating line 630).
Green button and heat generation lock (operating lines 376 and 473) continue to
be active.
8
Output setpoint wood-fired boiler
Output Ux is used for delivering a controlled demand for heat (DC 0…10 V). The
controlled demand for heat is matched based on the temperature acquired by
sensor B22. The control behavior is dependent on the settings made on operating
lines 381
EXP
through 383
EXP.
The heat demand is delivered only if the wood-fired boiler is released (according to
the “Lead heat source”, operating line 620, and “Release of the wood-fired boiler
below the outside temperature threshold”, operating line 632). The automatic heat
generation lock (operating line 473) continues to be active.
9
Temperature setpoint wood-fired boiler
Output Ux is used for delivering a voltage-proportional demand for heat (DC 0…10
V) (refer to operating line 891).
The heat demand is delivered only if the wood-fired boiler is released (according to
the “Lead heat source”, operating line 620, and “Release of the wood-fired boiler
above the outside temperature threshold”, operating line 632).
Green button and automatic heat generation lock (operating line 473) continue to
be active.
