APPENDIX 1 Multi staged HVAC theory of operation for the CT100
Staging for 2 stage normal or heat pump Cool
Target Temperature Maintenance in COOL -
If the room temperature is within the target temperature plus the
DIFF setting, the irst stage of cool will turn on. If the target temperature is not reached within 15 minutes, the
second stage of cooling will turn on and join the irst stage to reach the target temperature.
Target Temperature Recovery in COOL-
If the room temperature is beyond the new target temperature plus
the DIFF setting, the irst stage will turn on. Ten seconds later, the second stage will turn on with the irst stage
to help reach the new target.
With FAST recovery, both stages stay on until the new target temperature is reached. With ECON recovery,
both stages stay on until the DIFF setting is reached. Then, the second stage shuts off and the irst stage stays
on to the new target.
Staging for 2 stage normal Heat
Target Temperature Maintenance in HEAT -
If the room temperature is within the target temperature minus
the DIFF setting, the irst stage of heat will turn on. If the target temperature is not reached within 15 minutes,
the second stage of heat will turn on and join the irst stage to reach the target temperature. Example: Target
temperature 70F, DIFF at 2F, maintenance occurs at room temperatures of 69F and 68F.
Target Temperature Recovery in HEAT-
If the room temperature is beyond the new target temperature minus
the DIFF, the irst stage will turn on. Ten seconds later, the second stage will turn on and join the irst stage
to help reach the target temperature.. With FAST recovery, both stages stay on until the target temperature is
reached.
With ECON recovery, both stages stay on until the DIFF setting is reached. Then, the second stage shuts off
and the irst stage stays on until the target temperature is reached.
Staging for a 2 stage Heat Pump with no auxiliary heat
Target Temperature Maintenance -
If the room temperature is within the target temperature minus the DIFF
setting, the irst stage heat pump will turn on. If the target temperature is not reached within 15 minutes, the
