WaRnIngThis Heat-Timer control is strictly an operating control; it should never be used as a primary limit or safety control. all equipment

must have its own certified limit and safety controls required by local codes. The installer must verify proper operation and correct any

safety problems prior to the installation of this Heat-Timer control.

WaRnIngThe boiler/water heater must have its operating and limit controls installed and wired in a way so that the Supply sensor fault or DHW Energy Saver communication Error will

not cause a hazardous situation. It is the responsibility of the installer to make sure of the system operation and users safety during sensor fault or communication error.

Heat-Timer recommends the installation of a precision tempering valve, ETv, or TMC to help protect the output from excessive temperatures.
