Auto And Override (To Fully Open) - KMC Controls CTE-5202 Application Manual

Auto and Override (to Fully Open)

Adding a SPDT relay or switch enables overriding
the air flow to fully open. (Otherwise the example
below is the same as the cooling configuration in
Cooling or Heating on page
The SPDT relay selects one of the two modes (Auto/
Open). In the relay position shown below (Open),
the controller will override the flow setting. (Jump-
ing "2-10 IN" and "16 VDC OUT" drives the CSP-
4702 fully open.)

NOTE: If a maximum limit was set in the CSP-4702
controller, the damper will only open to
the maximum limit setting. See also the
Operation Test section of the
Installation
When the relay switches to Auto, the thermostat will
then control the VAV box based on demand.
