6.2. Back-up System
The back-up system included with the ICS- is exactly the same unit that comes standard with our
Contactor Control System (CCS™). This unit works independent of the controller, and can
activate any of the stages.
6.2.1. General Description
The back-up system has its own sensor which allows the board to continuously monitor
house temperature separately from the controller. If this temperature should exceed the
limits set by the controller, the back-up system would engage the appropriate equipment.
(For example: If the temperature is below the low limit setpoint, the back-up board
would engage all heat stages.)
Note: If power to the back-up board is lost, all stages will turn on.
The back-up board allows for a two step cool stage engagement. For a description of the
two step cool stage option, see section 6.2.3.2 below. If you want to use the two step
option, you will need to change the wiring inside the panel. For a diagram, see the
drawing on the next page.
6.2.2. Controls
The back-up system has three controls: Two temperature limit knobs, and a reminder
reset button. The temperature knobs are labeled “High Limit” and “Low Limit”.
6.2.2.1. High Limit
If for some reason (lightning, voltage fluctuations, etc.) your controller should
quit functioning, or function improperly, the back-up system in your CCS panel
would take over if temperature exceeded the limits. If the temperature felt by
