Heating mode:
Setting of the room sensor to "Automatic" or "Normal mode". The heating
circuit pump
A1
and the burner demand via the
COP 1
control output are only switched off by
the pump switch-off parameter (menu
PUMP
).
Cooling mode:
Room sensor setting to "Cooling mode". The pump
A1
and the cooler de-
mand via the
COP 2
control output are always active. The mixer control via the outputs
A2
and
A3
takes place
inversely
(mixer opened upon increasing temperature) and the set set
temperature
TNC
(parameter menu).
All pr1:
Like program 128, but the switchover does not take place via the slider switch of the room
sensor rather via the external switch
S5
and the heating/cooling demands via the external
switch
S6
.
In the
SENSOR
menu, the sensors
S5
and
S6
must be set to "
DIG
".
The digital sensor
S5
(external potential-free switching contact) determines whether heating
or cooling operation is required. If the switch is set to "
ON
", then heating operation applies, if
it is set to "
OFF
", then cooling operation applies.
Using digital sensor
S6
(external potential-free switching contact) in heating mode, the burner
demand is activated via control output 1 while in cooling mode the cooler demand is activated
via control output 2. If the switch is switched on, the demand is active.
The cooling operation functions only in combination with the RASPT or RAS room
sensor.
All pr2:
Like program 128, however a buffer cylinder sensor
S4
is used. This sensor delivers sepa-
rate switching thresholds for the release of the pump and the burner or cooler demand.
Heating mode:
A1 = S4 > min1 & (heating = active)
COP 1 = S4 < max1 & (heating = active)
The set flow temperature is calculated according to the
heat curve
.
Cooling mode:
A1 = S4 < max2 & (Room sensor = "Cooling mode")
COP 2 = S4 > min 2 & (Room sensor = "Cooling mode")
The set flow temperature corresponds to the parameter value
TNC
.
