Function and description
The
UFH-MASTER
with 6 zones is a wiring module with built in pump logic. All the main electrical connections for water floor
heating system are existing. This box can be adapted either on a DIN rail or directly on a wall. (the DIN rail mounting perm it
to add with facility a
UFH-SLAVE
or
UFH-H&C
module).
It connects room thermostats to their corresponding actuators.
The state of each zone is indicated by individual green LED.
As soon as we have a heat demand from one zone a relay with 2 potential-free contacts is switch on (pump, boiler or other
possible connection).
By using terminal A and B, the pilot wire of thermostats can be controlled by a main zone programmer (
UFH- DIGITAL
PROGRAMMER 24V
).
