Thermolec Application &Technical Notes - Manual (Page 62)

ZONE HEATER
Application # 1
Central ventilation with zone heaters.
In this application, there is no furnace required but only a
central blower that provides continuous ventilation. The heating
of the forced air is done in each zone, controlled by an accurate
electronic thermostat supplied with each heater.
Each thermostat controls it’s heater in a proportional way, thus
avoiding a waste of energy and providing maximum comfort.
The super-sensitive air flow sensor permits the heater to
operate only when the fan is running.
The central blower should be equipped with an air filter, a
humidifier and a cooling coil if air conditioning is required.
Application # 2
Add-on heater for a cold room.
In a central heating system, it often happens that a room
located at the end of a duct run is too cold and
uncomfortable. This could also happen to a basement in
mid-season. The THERMO-ZONE is a perfect, easy and
low cost solution. Just insert the new heater in the duct
supplying that cold room and enjoy new comfort.
This new heater is equipped with a modulating
controller which uses the minimum amount of energy,
thus avoiding waste, and a super-sensitive air flow
sensor which permits the heater to operate only when the
fan is running.
This heater is supplied with an electronic wall thermostat
to maximize comfort and savings.
It is recommended to keep the fan in continuous
operation at low speed.
