REMOTE CONTROL INSTALLATION AND OPERATION CAUTION: Before installing remote controls to the AFT thermostat model heaters, read the following: The digital thermostat model is remote-ready in most cases. The digital liquid crystal display (LCD) shows the actual pool temperature, operating status, and service codes (See examples below). The touch pad on the control panel allows you to select the desired pool or spa temperature. It also indicates when a remote system is controlling the heater by displaying Remote in the display. When connecting the heater to a remote system, identify whether it is a two- or three-wire remote system. Select the appropriate instruction listed below to properly install the remote to the heater. OFF Mode Heating in the POOL Mode Heating in the SPA Mode Remote Mode 7-PIN Remote Interface Harness Pool Common (BLK/ORN) Spa Common (ORN/BLK) 24VAC HOT (BLU) ACTIVATING THE REMOTE To activate or deactivate the remote function, follow these steps: Press and hold the UP and DOWN arrow buttons for 3 to 5 seconds. REMOTE OPERATION The AFT model heaters are equipped with the ability to work with external remote controls. The supplied 7pin remote wiring connector supplies power out to either a toggle switch or the switch contacts of a third party remote. The remote works by either making or breaking the circuit created by the remote wiring. Typically, a remote does not supply power to the heater, it only provides a switching function to turn the heater On or Off. If your remote is supplying its own voltage to the heater, it will not work with this heater and may damage the digital circuit board. The second line of the display will alternate even when the unit is off ("No Demand"). For operation of the heater using the onboard thermostatic controls with a time clock, see the "Time Clock / Fireman's Switch" section. NOTE: When in remote operation, the keypad mode and temp buttons are disabled. Note: Electrostatic Discharge (ESD) damage can be caused by direct or indirect contact with the wiring or circuit board. When one walks to the heater area, an electrostatic charge accumulates on the body. Contact of a finger allows the body to discharge, possibly causing device damage. This damage can be limited if the service person discharges himself, following ESD preventive/removal practices, and holds on to the heater enclosure for 5 seconds before proceeding. 36
