Thermostat
Adding a SPDT relay or switch enables overriding
the air ow to fully open or fully closed. (Otherwise
the examples below are the same as the cooling
conguration in Cooling or Heating on page 33.)
The “Override to Fully Closed” wiring diagram
below allows the CTE-5202 thermostat to control the
CSP-5001 controller as normal (auto) or override the
ow seing to fully closed.
The SPDT relay selects one of the two modes (Auto/
Fully Closed). In the relay position shown below, the
controller will override the ow seing. (Jumping
“–” and “IN” drives the CSP-5001 fully closed.)
NOTE: If a minimum limit was set in the CSP-500x
controller, the damper will only close to the
minimum limit seing.
When the relay switches to Auto, the thermostat will
then control the VAV box based on demand.
The “Override to Fully Open” wiring illustration
below allows the CTE-5202 thermostat to control the
CSP-5001 controller as normal (Auto) or override the
ow seing to fully open.
In the relay position shown, the controller will over-
ride the ow seing. (Jumping “16 VDC” and “IN”
drives the CSP-5001 fully open.)
NOTE: If a maximum limit was set in the CSP-500x
controller, the damper will only open to the
maximum limit seing.
When the relay switches to Auto, the thermostat will
control the VAV box based on demand.
(See also the Auto, Override to Fully Closed, or
Override to Fully Open section with a CTE-5101 in
the CSP-5001/5002 Applications Guide.)
