This setting adjusts how long the CoolBot heater waits before kicking back on. If you are having ice-ups you can try increasing this setting 1 point at a time. Increasing this setting will run the AC compressor less frequently, which will lessen any freeze ups. By default we are set to "d1" the CoolBot will wait 30 seconds before kicking on after it senses thermostatically that it should cycle on.
The heater delay can be set from 0-10, 30 or 60. A setting of 0 is no delay, 9 is very long, and 60 is the longest.
A "PU" message in the heater field means that the heater is pulsing and the heater light is blinking
