89Eaton RF-System

Connection to a Multi-Heating actuator:

A Multi-Heating actuator can be connected with its 12 heating inputs either to Heating-request,

Cooling-request or combined as Heating-/Cooling-request. Per room as much channels of the

same type as desired can be connected.

To make sure that the Room-Manager and the Multi-Heating actuator always are in the same

operation type the Room-Manager channel „Operation type output“ needs to be connected to the

channel „Heating/Cooling“ of the Multi-Heating actuator. (for details see Operation-Mode and –

Type toggle of the Room-Manager).

Rooms of the Room-Manager that are exclusively connected to Multi-Heating actuator inputs do

not affect the status of the Sum requests (Heating and cooling). The Multi-Heating actuator has its

own sum output which should be used to control a pump etc. Another reason is that the regulation

of the electrical valves takes place in the Multi-Heating actuator and the Room-Manager only

provides the Set- and Actual-temperature for each input with 2 separate RF-commands.
