Infloor Thermostatic regulating unit 31093-31094 - Manual

Thermostatic regulating unit for
underfloor radiant panels
Function
The thermostatic regulating unit is designed for maintaining the
temperature set for the flow fluid constant in a low temperature
circuit for underfloor radiant panels.
This unit has been specially designed for use with both the external
and wall embedded versions of the separator/distribution
manifolds.
It comes supplied with a three-way thermostatic mixing valve with
built-in temperature sensor, a three-speed pump, a safety
