UTREC + UNITS are equipped with special internal section for the

bypass function.

When the air intake temperature is near the air outlet temperature the

heat recovery unit can be partly bypassed reducing the heat exchange.

The unit could be equipped with manual opening sysyem (standard) or

with optional electric motor: the automated configuration can be mana-

ged by an external input or by integrated electronical management

(optional)

 When the intake air is very cold, frost may form on the heat

recovery unit.

By installing an additional pressure switch with the RMS accessory, the

heat recovery defrosting can be controlled.

When the pressure loss registered by the pressure switch is too high, the

dampers A and B will close and the damper C will open.

So the warm return air is recirculated, allowing the heat exchanger defro-

sting. Afterwards the unit functioning will become normal.
