Sensors
Plug Sensor
F0.1/F0.2 Outside temperature sensor
F0.2/F0.3 Radio clock receiver (accessories)
F4 Buffer temperature sensor
F6 Cylinder temperature sensor, top
(X25.5/X25.6)
F7 Cylinder temperature sensor, bottom
(X25.7/X25.8)
F11 Contact humidistat 24 V
Note
If a 230 V~ contact humidistat (connection to X3.8/X3.9) is used
for cooling, insert a jumper, otherwise the heat pump will not
start (message "CA Protectn device primry").
F13 Flow temperature sensor, system (downstream of the heating wa-
ter buffer cylinder and external heat generator)
F14 Flow temperature sensor, cooling circuit (heating circuit without
mixer A1/HC1 or separate cooling circuit SKK)
F16 Room temperature sensor, cooling circuit
■

F20 Boiler water temperature sensor, external heat source

(cont.)
–
Required for separate cooling circuit SKK
Recommended for heating/cooling circuit without mixer A1/HC1
Explanation
Connection values
Max. output: 130 W
■
Voltage: 230 V~
■
Max. switching current: 4(2) A
■
In systems without a heating water buffer cylinder, no
■
other heating circuit pump is required (see terminal
212.2).
Connect the temperature limiter to restrict the maxi-
■
mum temperature for underfloor heating systems in
series (see page 23).
Secondary pump is connected at the factory. Connect
the temperature limiter on site.
