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 permit 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).
