Contactor Control Systems

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
will turn stages on or off if temperature exceeds the high or low limits. If the
temperature felt by the sensor reaches one degree above the high limit, the back-
up board would start all stages set to cool one. (This could be any, or all of your
cool stages.) If temperature continues to rise, the back-up would then start cool 2
(all other cool stages). This should lower temperature below the setpoint.
If you use the unit as shipped, the back-up system would engage all cool stages
at the same time.
Note: If you want the two step cooling option, you will need to wire the panel as
shown in the drawing on the next page.
6.2.2.2.
Low Limit
If your house temperature drops below the low limit, all heat stages would be
turned on by the back up board until temperature is brought back up to the low
limit.
6.2.2.3.
Reminder Reset Button
The last control on the back-up board is the reminder reset button. During a
growout you lower house temperature as your animals mature. It is vitally
important to reset your high and low limits as well. If you did not reset your
back-ups, the difference between target temperature and the back-up setpoint
could reach 30 to 40 degrees. The reminder alert buzzer warns you to check your
back-up setpoints every five days. Note: It is important to check your back-up
setpoints daily.
