power supply to protect the unit, stops the unit and creates overheat alarm. The unit runs the fans for a preset
time after the heater is stopped in order to cool down the heaters. Press RESET button inside the unit to reset
protection.
Heating water connection
For the correct operation of the ventilation unit, it is necessary to make hot water connections to the heating
coil. To avoid freezing, the water temperature must be adjusted accordingly to the outdoor air temperature.
Pressure sensor
Pressure sensor is used to measure duct supply and exhaust static pressure. When units is used with duct
pressure control, and VAV dampers, then duct pressure measurement should be located on ductwork.
For this, supply and extract pressure measuring pipes should be rerouted and connected on the duct. The
sensors must not be positioned in, or in the vicinity of a duct bend.

If the building is left unheated for longer period during cold conditions, the water must be drained
from pipe and heating coil.
