Preheat; Using The Override Function - Rinnai RCE-671TR Operation Manual

TIMER OPERATION - AVENGER & DYNAMO

PREHEAT

This function operates automatically in
conjunction with the Timers. When a Timer is
selected, the heater may operate anywhere
within an hour prior to the programmed
starting time of a Timer.
This function is called Pre-heat since it
ensures the room reaches the desired
temperature by the On Time programmed
into the Timer(s). The room temperature is
sensed one hour before the programmed On
Time.
The temperature differential at the time of sensing the room temperature combined with the data from
previous operation governs exactly how long before the programmed On time the micro-computer will
operate the heater and ignite the burner.

USING THE OVERRIDE FUNCTION

This function is used to manually override the current operation of the heater. For example: if the
heater is between the finishing and starting times of a timer program and the Override button is
selected, then the heater will begin to operate and heat the room.
The heater must be between the finishing and starting times of a timer program for the Override to
function to work. Either of the Timer indicators
