SECTION 3. INSTALLATION REMOTE CONTROL CONNECTIONS: A terminal block is provided in the H-Series heater control compartment for connection of a remote control system. Remote wiring should be run in a separate conduit. Do not run remote wiring parallel to high voltage wires. ELECTRONIC HEATERS: Use 22 AWG wire for runs less than 30 feet. For run over 30 feet, use 20 AWG wire. Runs should not exceed 200 feet. The terminal block for connecting remote switches is located to the right of the electrical junction box. The dipswitch for disabling the heater's temperature thermostat is located on the circuit board. The setting of this dipswitch may need to be changed depending on the type of remote that is connected to the heater. 2-Wire Remote Thermostat: This type of remote has its own temperature sensor for regulating the water temperature. To disable the heater's thermostat, set the bypass dipswitch to the "on" position. Wire the remote to terminals 1 & 2 of the terminal block. Do not remove the jumper clip on terminals 4 & 5. To operate the heater by remote thermostat, the heater's control must be in either the "Pool" or "Spa" mode. The heater's display will show "bO". The "Pool" or "Spa" LED will be illuminated. The heater will fire when instructed by the remote thermostat. The heater's thermostat will function to limit the water temperature to a maximum of 104° F. 2-Wire Remote Switch: This type of remote allows for the heater to be remotely turned off or on. The heater uses its internal thermostat to regulate the water temperature. Connect this type of remote to terminals 4 & 5. Remove the jumper clip from 4 & 5. The bypass dip-switch should be kept in the off position. The heater's internal thermostat will regulate the water temperature. Whenever the remote switch is off, heater will be disabled and the display will show "LO". 3-Wire Remote Switch: A 3-wire remote allows for the "Pool" or "Spa" modes of the heater to be remotely selected. The heater uses its internal thermostat to regulate the water temperature. Connect Pool/Low of the remote to terminal 1, Common to terminal 2, and Spa/High to terminal 3. Do not remove the jumper clip on terminals 4 & 5. The bypass dipswitch should be kept in the off position. To operate the heater with a remote 3-wire switch, the heater's control must be in the "Standby" mode. The Standby LED will be illuminated. When the remote switch is set to "Pool/ Low", the Pool LED will be energized and the display will show the Pool water temperature. When the remote switch is set to "Spa/High", the Spa LED will be energized and the display will show the Spa water temperature. The heater will use its internal thermostat to regulate the water temperature to the set point of the mode selected. MILLIVOLT HEATERS: A terminal block for connecting 2-wire remote thermostats or switches is located on the Intermediate Panel. Use a high quality 22 AWG wire with corrosion resistant connections. Runs should not exceed 25 feet. After hook-up is complete, turn thermostat to its maximum setting and move the system switch to on. 17
