Dimplex R15/104 - 15kW - Manual (Page 2)

USER INSTRUCTIONS
PRINCIPLES OF OPERATION
The warm air system is designed to operate on cheap rate electricity.
The heater takes in energy when electricity tariffs are low, and
retains it in the insulated core. Warm air is provided directly from
the unit mounted on a plenum or through duct work, by the operation
of a fan. The fan may be controlled by a central thermostat and/or
a time clock.
SAFETY INSTRUCTIONS
1. VENTILATE ROOM WELL DURING COMMISSIONING
2. DO NOT MOVE THE HEATER IN ANY WAY ONCE INSTALLED,
WITHOUT THE SERVICES OF A COMPETENT ELECTRICIAN.
3. DO NOT COVER THE HEATER WITH CLOTHING ETC. AT ANY
TIME, OR POSITION FURNITURE CLOSE TO OR AGAINST
THE HEATER.
ALSO REFER TO COVER PAGE
COMMISSIONING
The heater should be commissioned in accordance with the
installation instructions - by the installing engineer.
CONTROL FUNCTIONS - see Fig. A
1. INPUT CONTROL
The input controller is a thermostat which regulates the amount
of energy taken by the heater during the hours when cheap
rate electricity is available. Turning the knob clockwise increases
the amount of heat stored. The setting should be adjusted from
MIN to MAX to suit seasonal requirements.
2. NEON INDICATOR & 3. FAN SWITCH
To obtain heat from the Electricaire Unit press the fan switch to
the ON position. The fan indicator light will now glow red. If the
fan is controlled by a room thermostat it will switch off
automatically when the room temperature reaches the required
level. The fan should be switched off before retiring at night.
This function may be performed by installing a time clock.
4. BOOST SWITCH
The boost switch increases the airflow delivered by the
Electricaire Unit. This facility is designed to produce a rapid
rise in room temperature, e.g. first thing in the morning or when
you return home in cold weather.
5. DAY ENERGY SWITCH
If your Electricaire Unit is connected to the “White Meter” tariff
the day energy switch operates direct acting elements. This
facility extends the heat output obtainable from the Electricaire
Unit by using day energy after the core has been fully discharged.
To avoid unnecessary use of day rate energy the following
safeguards have been built into the appliance.
Day energy can only be used if:
The Day Energy switch is in the ON position.
The fan switch is in the ON position.
The outlet air temperature has fallen below a pre-determined
level.
In addition ensure the input is set at MAX.
