SEQUENCE OF OPERATIONS
THERMOSTAT CONTROL
FAN SPEED CONTROL
These units are equipped with variable speed supply fan
control. There is a cooling and heating fan speed set
point. In this application, both the cooling and heating fan
speed set point should be the same. This should be set by
the test and balance contractor to provide and correct CFM
for the unit. Once the supply fan speed is initially set, it will
not modulate.
NORMAL HOURS (not night set back)
Cooling Mode(humidistat on cooling) –When the
temperature gets above the set point temperature by more
than 2 degrees, the compressor will come on and start
cooling the air. Once the temperature reaches the set-
point, the compressor will turn off and the air will continue
to circulate in the space without heating or cooling.
Heating Mode (humidistat on heating) – When the
temperature gets below the set point temperature by
more than 2 degrees, the heat pump will come and begin
heating the air. Once the temperature reaches the set
point temperature, the heat pump will turn off and the air
will continue to circulate in the space without heating or
cooling.
Humidity mode – When the unit is not running in cooling
or heating and the humidity sensor on the humidistat
registers a humidity higher than the set point humidity, the
compressor will come on for cooling and the hot gas on/off
valves will open to raise the discharge temperature of the
air entering the building after cooling. This will help reduce
the humidity without cooling the building off too much.
Once the humidity is below the set point humidity, the unit
compressor and hot gas on/off valves will shut off and the
air will continue to circulate in the space without heating or
cooling.
NIGHT SET BACK HOURS
Allows the occupant to set a schedule across the 7 day, 24
hour week to schedule set back temperatures at night to
conserve energy.
UNOCCUPIED HOURS
Allows the occupant to set a schedule across the 7 day, 24
hour week to schedule the unit off to conserve energy.
