2.3 Product description
2.3.1 Functions
You can use the basic unit 24 V for electronic control of your surface
heating. The basic unit converts the information by the connected room
thermostats to control signals for the actuators.
This function is guaranteed in combination with:
n
room thermostat model 1243.1 or 1243.4
n and actuator model 1249.1
The basic unit controls all functions of the system and converts the
measured value transmitted by the room thermostat to control signals
for the actuators. For the operation of the basic unit, a 230 V mains connection must be provided in the manifold cabinet.
To ensure proper functionality of the pump control, actuators with the
property "closed in de-energised state " are required.
The basic unit is connected to the mains by means of a separately available power pack (model 1247.5)
verts the 230 V mains voltage to 24 V.
Ä „Power pack“ on page 9
which con-
All actuators and room thermostats connected via cable are directly
supplied with the required operating voltage. Additional mains connections are not required.

Features
Product information
n Simple plugging / clamping solution
n Connections per room thermostat (zone)
– 2 actuators (standard)
– 4 actuators (optional, max. 2 x)
n Connection for control of one circulation pump
n Connection for one external time switch
n Connection for room thermostats with time switch
Optionally, you can transmit the signal of the room thermostat to two other actuators (terminal 2 and/or 5) at terminal 1
and/or 4. In this case, one thermostat each in total can be
used.
System components required
For using the single room regulation in combination with a basic unit,
please order the specified number of the following components in addition:
n
room thermostats – model 1243.1 (analogue) or 1243.4 (digital)
n actuators – model 1249.1
n power pack – model 1247.5
