NOBO PANEL RADIATORS
SERIES '8' PANEL HEATER TYPES - OPERATION NOTES
Microprocessor control provides the heart to the Series 8 Panel heater.
Offering a wide range of options in control technology.
The plug & play approach creates a versatile and flexible choice.
The use of a microprocessor allows precise temperature regulation operating the proportional principal.
Control of temperature is divided into two modes of operation. Pre-heat mode and maintain mode.
In pre-heat mode the processor allows the heater to full-burn but without over-heating.
Maintain mode takes over when the room temperature is within one degree of the thermostat set-point.
In maintain mode the processor cycles once in every minute and allows
the heater to burn for part of that minute. The closer the room temperature
gets to the set-point the shorter the burn-time becomes.
The proportional process of temperature regulation provides a cooler heater
giving a gentle heat with better air quality and efficient use of energy.
It is far better to have a bigger heater and control the heat output, than to have
a smaller heater that has to run flat-out for most of the time. Where a room
has more than one heater, all of the heaters should be used together and the control settings should be balanced
so that they all operate at the same temperature. It is not considered to be good practice to have one heater
operating at a higher temperature than another or for one heater to be switched off leaving the other to do all of the
work. It is considered to be far better to make use of the set-back facility, maintaining a background temperature
and switching up to comfort level during periods of occupation, so that rooms are not allowed to get too cold.
The temperature setting of the heater/s should be adjusted to
provide the required room temperature, as shown above.
The settings shown on the left where the adjustments are to
opposite extremes are not recommended because this causes the
heater to run flat-out for long periods producing high air leaving temperatures which can lead to discolouration.
Best results are achieved when the heater is allowed to operate in the proportional band, where the heater
burns intermittently, producing a much cooler heater and lower air leaving temperature.
Discolouration may occur in rooms where there is smoke or air pollution, the burning of candles
or combustion of any carbon based material will produce soot deposits. The convection current
created by warm air leaving the heater will circulate the air within a room and any fumes or pollution
in the air will also be circulated through the heater. The effects of air pollution are
made worse when heaters are allowed to operate flat-out for long periods. A heater
will have to work much harder if adjacent rooms are unheated, the Hall for example.
Heaters should be kept clean and may be tilted forward to gain access to the back for cleaning &
decorating. Pressing down the two retaining clips on the bracket at the back will enable the top of
the heater to be drawn forward. The heater may be
cleaned with a damp cloth and mild detergent.
It is important that sufficient clear space is allowed
for heat to be freely dissipated from the heater.
Furniture should not be placed close to the heater,
nor should anything be draped over the heater
that will in anyway restrict the air leaving grille, which
should, at all times, remain completely clear. Covering
a heater creates a fire risk and may cause a fire.
