Analog Controls Installation and Balancing Procedures
The Analog Electronic Control System is a pressure independent volume reset control that uses a
KMC CSP-4702 controller-actuator (see Figure 10).
Figure 10 ā Analog Controller CSP 4702
Adjustments for the minimum and maximum airflow settings are made at the thermostat. The
thermostat (CTE-5202) operates on a 16 VDC power supply from the CSP 4702 controller and
outputs a 0 to 10 VDC signal on the AO1 and AO2 terminals. AO1 is used as the cooling output
and AO2 is used as the heating output.
Thermostat Installation
For proper operation, mount the thermostat on an interior wall. Do not mount the thermostat in a
location that will cause it to be affected by direct sunlight or other heat or cold sources. The
thermostat should be clear of all obstructions so it can properly sense the room temperature.
Complete rough-in wiring at each location prior to thermostat installation. Cable insulation must meet
local building codes.
1. Remove thermostat cover. If the thermostat is locked on the back plate, turn the hex screws in
the two outermost holes on the bottom of the cover CLOCKWISE into the back plate until they
just clear the cover. Do not remove these screws completely. Swing the thermostat up and
away from the back plate to remove it.
2. Route the wires through the opening in the back plate.
3. Install the back plate directly to the junction box using the screws supplied with the thermostat.
Verify the hex screws used for securing the cover are located at the bottom before installing.
