Remote Control Station Installation
The remote control station should be mounted approximately
5 feet above the floor on a stationary vertical surface. The
dampers should be checked for proper operation after all of
the electrical connections have been made. The recirculation
dampers will be closed and the damper in the head will be in
the full open position in the exhaust mode. In the supply
mode, the dampers will modulate by adjusting the temperature
selector. The dampers should operate freely without binding.
The control station will have a temperature selector and an
on/off switch.
Three-Way Motor Actuated Dampers
Three-Way Heat Savers utilize three dampers, two normally open dampers mounted vertically on opposite sides for recirculation
and one normally closed damper mounted horizontally in the top of the unit just below the fresh air intake/exhaust head. The
three dampers are connected to one modulating motor. For recirculation, they are positioned by the discharge temperature control
to recirculate all or part of the air and introduce outside air to satisfy the desired temperature. For exhaust, the damper motor is
driven fully open, closing the side dampers and opening the top damper. The damper actuating rods are left unconnected on the
side recirculating dampers to facilitate shipping and easy installation. They must be reconnected to the dampers prior to start-up.
No adjustment is necessary. The damper in the head is normally closed and the recirculating dampers are normally open when the
actuating rods are connected.
