OPERATING THE TIMER(S) Before operating the Timer(s), the clock time must be correct, and a starting time and finishing time for the Timer(s) must be programmed. See pages 14 and 15. The two Timers operate in the same way. This heater does not commence operation at the programmed starting time. It will attempt to heat a room by the programmed starting time. See Pre-heat page 17, for further explanation.
PRE-HEAT 1 This function operates automatically in conjunction with either of the Timers. When a Timer is selected, the heater may operate anywhere within an hour prior to the programmed starting time of the Timer. The Pre-heat function will heat a room to the pre-set temperature by the programmed On Time. This function is called Pre-heat due to the way it operates. The room temperature is sensed one hour before reaching the programmed time of either Timer.
OVERRIDE FUNCTION This function is intended to be used to manually override the current operation of the heater, For example; if the heater is in standby mode (i.e. between finishing time and starting time of a Timer), and the Override button is selected, then the heater will begin to operate, and heat the room. 1 To operate the Override simply press the Override button.
