Operation
The thermostat communicates with the wireless damper
actuator via an RF wireless data link. It monitors the space
temperature and the setpoint temperature and sends data to
the damper telling it how many degrees the space temperature
is above or below the temperature setting.
The actuator has a temperature sensor that monitors the
supply air temperature to determine if the HVAC system is or
has been calling for heating or cooling. The damper then
opens or closes proportional to the temperature differential it
received from the thermostat.
The thermostat periodically adjusts the airflow. The interval
can be set from 5 to 30 minutes. The change in airflow can be
set to either 8% or 16% per degree of temperature differential.
Energy Savings
The wireless thermostat and damper are used to automatically
control airflow to maintain a comfortable temperature and
eliminate the annoying overcooling and overheating found in
many work areas, offices, restaurants and other spaces.
Excess airflow that caused the overcooling or overheating is
automatically redirected to areas that need it and the
thermostat is satisfied sooner, resulting in less operating time
for the HVAC system.
The thermostat has an Off position that can shut the airflow
down when the office or space is not being used and provide
even greater energy savings. The night setback feature works
the same way and provides added energy savings.
Improved Comfort
The WCD Damper actuator has a Close position limit that can
be used to insure a minimum airflow even when the thermostat
tries to fully close the damper. The minimum Close position
can be set from about 50% closed to fully closed.
This should be used when a large number of WCD Dampers
are used with the same HVAC system to insure that static
pressure does not damage the ducts.
See the Installation Instructions supplied with the WCD
Damper for setting the Close position limit.

The thermostat can be installed on any interior wall
approximately 5 feet above the floor. To insure accurate
reading of the space temperature, the thermostat should not be
in direct sunlight.
Install the sub-base using two #8 or #6 sheet metal screws
with wall anchors where required. Level the thermostat for
appearance.
