Multi-Heating actuator

The Multi-Heating actuator is a mains supplied device that can be used to control electrical valves

for Panel heating- and cooling-systems (Floor heating,…). Up to 12 different zones and a

maximum of 14 vales can be controlled by the device.

It has 12 inputs for Set- and Actual temperature, a sum output, an error output, a binary input for a

dew point sensor and an input for Heating/Cooling toggle.

The temperature information for the each of the 12 inputs can either be sent by a Room-controller

(Type CRCA-00/06 or CRCA-00/07), a Room-Manager, a Home-Manager or other intelligent

devices like Ethernet CI, USB-RF-Communication-Stick etc.

In the configuration window of the Multi-Heating actuator (right click on the device symbol and

selection of „configuration“) you can find information about the connected devices for each channel

and the Software- and Hardware-Version of the device.

Detailed information about the connection of the electrical valves and the different wiring

possibilities can be found in the mounting instruction.

General information about the different channels of the Multi-Heating actuator:

Heating inputs 1-12

Inputs for Set- and Actual-temperature from

Room-controllers, Room-Manager etc.

Sum output:

Output that can be connected to any actuator (for

controlling a pump etc.). Its state depends on the state

of each of the 12 valve outputs.

Error output:

Output that can be connected to any actuator. It will be

ON if any error occurs (no temperature information, low

battery of connected sensors etc.)

Input: dew sensor

Input for a binary dew point sensor. If it receives an ON

message cooling is not allowed.

Input: Heating/Cooling toggle

Input for the toggle of the operation type between

Heating and Cooling (OFF=Heating, ON=Cooling)

Operation with Room-controller:

In this case one or more Room-controller (Type CRCA-00/06 or CRCA-00/07) are used to provide

the Room- and Set-temperature. Each Room-controller can be connected to multiple inputs of the

Multi-Heating actuator but each input can only have one connection. The Room-controller needs to

be set to the Mode „Send temperature value“.

The values of the Set-temperatures for Comfort and Eco mode can be set in the configuration

window of the Room-controller. Using the Mode-switch on the Room-controller you can toggle

between comfort and Eco mode. Additionally the set value can also be changed by the customer

between +3°C and -3°C using the control wheel.
