pump, evacuate the system from both the low
and high side of the system to 500 microns
and ensure that the system holds at the
vacuum pressure. If not, check for leaks and
evacuate again. If the vacuum is maintained, add refrigerant to raise the pressure to 2 psig,
and either open the service valves (suction
first) on pre-charged condensing units, or add
refrigerant to the system until the proper
operating charge is obtained.
ELECTRICAL .
The DCC7235 is a microcontroller-based electronic volume controller for brushless dc motor-driven fan
coils, furnaces or other systems. It commands discrete or variable blower speeds, torques or airflow in
heating, cooling and ventilation modes from inputs provided from a discrete or proportional thermostat or
controller whose switched 24VAC signal outputs activate a blower's air volume. Discrete output blower
command values are selected and scaled from tables, individually selected by dip-switches. One controller
can be used with several different products of different capacities. An on-board dip-switch optionally selects
a 0-10V input for variable/proportional volume control. The DCC7235 can be used with proportional, 1-
stage HEAT/COOL, 1 or 2-Stage COOL, and 1 or 2-Stage HEAT thermostats.
Five relay contact outputs are available for activating accessories. Two are high voltage, dry contacts.
Three others switch the 24VAC (“R”) powering the controller. One of those three can be isolated from “R”
by removing a shunt and providing 24VAC dry contacts.
