Instructions for Hydronic systems (continued)
This unit must be wired by a qualified electrician
in accordance with the National Electrical Code.
Using a new 24 volt transformer, a new 24 volt relay, and a low voltage wall thermostat
the following wiring diagram shows how to modify the existing boiler aqua stat wiring.
By adding a normal open circuit into the existing aqua stat wiring you can leave the
boiler aqua stat set at the original factory setting. Set the new low voltage wall
thermostat approximately 3 degrees below the wood heat thermostat. If the heater
were to get behind for any reason the boiler can come on and help maintain the
building temperature.
