FRESH AIR HEATER
Application # 3
Fresh Air make-up.
A THERMO-AIR heater combined with a small fan is
all that it takes to create a low-cost, efficient and
accurate air make-up.
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.
Remote set point adjustment option
Instead of adjusting the set-point on the electronic module inside the heater, it is possible to adjust it remotely by using
1- A remote duct thermostat (DT-1040) with a range of 10 to 40°C
or
2- A wall mount set-point adjuster with a range of 0 to 37°C (RA-037).
In both cases, it is necessary to set the potentiometer to the "R" position (for Remote Control).
