Generic Heating Features & Functions
There are many diering features that are available with Rinnai gas heating appliances. The following pages give an overview of
each feature, the benets gained and a brief explanation of how they work. For a specic list of which features apply to a particular
product, please refer to the specications starting on page 13.
Preheat Feature
This function will automatically operate the appliance before the programmed start
time of the timer, in order to heat a room to the pre-set temperature by the
programmed start time. This means that the heater may activate up to 1 hour prior to
the programmed start time.
Economy Button
The Economy (ECON) function is an energy saving feature. It gradually reduces the
heat settings once the room has maintained the set temperature for a period of 1
hour. Many people operate heaters at a higher temperature initially when they are
cold, but forget to turn them down later.
Thermostatic Heat Control
Often referred to as set’n’forget, thermostatic control means that the heater will
modulate up and down to ensure a set temperature is maintained, for greater comfort.
Manual Heat Control
This applies to heater models that have a number of predetermined settings that you
can select from. Some heaters have a Low/Med/High option while others can have up
to 6 manual settings.
Timers
Models with timers have one of the following:
Dual Weekday & Weekend Timers
Set the heater to come on and o in the mornings & evenings for the weekdays
Monday to Friday. Additionally, dierent times can be set for the weekend when
people prefer to get up a little later.
Dual Timers
Set the heater to come on and o in the mornings & evenings (or any other selected
dual periods). Timers are set separately allowing you to operate with both, just one or
none at all.
Multiple Timers (4 Periods)
Where 4 periods per day can be set at varying temperatures. Ideal for mornings when
waking and coming home of an evening, with the other 2 periods usually set as a
minimum desired temperature during the day and overnight. In addition, each day of
the week can have a dierent setting, making these timers the most exible available
Delay Timer (FDT)
This feature is only available with the “FDT” range of Energysaver Power Flued heaters
and is usually only used for commercial application such as schools etc. Factory
ordered & preset, the delay timer automatically shuts the heater o after a
predetermined (programmed) time of either 1, 2, 3, 6, 8, 10 or 12 hour intervals. As an
additional feature, a central relay timer can be programmed to operate multiple
heaters.
