Remote Control Connection - Hayward H250FDN Service & Installation Manual



REMOTE CONTROL CONNECTION:

The heater is equipped for connection to an external -wire remote thermostat or a -wire remote switch.
A -wire thermostat has its own temperature sensor for regulating water temperature. A - wire remote switch
allows the "POOL" or "SPA" models to be remotely selected. Connect remote wiring to the terminal block on
the exterior of the control box (see Figure A below). Do not remove the wire harness and attempt to connect
remote controls directly to the ignition control board. Remote wiring must be run in a separate conduit. Use
22 AWG wire for runs less than 30 feet. Use 20 AWG wire for runs over 30 feet. The maximum allowable run
is 00 feet.
