UNI TEMP is a constant
temperature controller. It is
designed for mounting on mixing
valve.
It is also equipped with mounting
kit for assembly on mixing valves
of other manufacturers.
Controller has a fixed angle
rotation of 90° and possibility of
manual control.
With DIP switches inside actuator
is possible to set the following
parameters:
- Direction of rotation (direct
CW / inverse CCW)
- Different temperature ranges
depending on the application
- Reaction factor x1/x10

It is intended for:
źmaintaining a constant temperature in boiler heating circuit (protection
against condensation),
źuse in under floor heating applications, industrial processes, heat
accumulators,
źuse in domestic hot water systems or swimming pools (individual
systems, SPA, public swimming pools).
