In addition to showing the status of the snow/ice melting system and controlling the hold-on time, the RCO will turn on/off the heat for these controllers.
Note: When the Heater Cycle switch is momentarily depressed, it will start a manual Heater Cycle for the Cycle Time setting. Momentarily depressed while heaters are being operated by a Hold-On Timer or during manual Heater Cycle will end the Heater Cycle. Heater operation during snow conditions cannot be canceled in this manner.
