10. Correct Placement of the Control Thermostat
The mounting height restriction that is normally included with a standard room thermostat can be
ignored with ILO Heating Panels. In a room that is warmed by ILO’s far infrared heaters, the
thermostat may be located at any level between 1 foot (30cm) above the floor, to 1 foot (30cm) below
the ceiling because the typical floor to ceiling temperature difference is only 3.5 to 5.5°F (2 to 3°C).
Standard room thermostats are designed to measure a representative air temperature, which is
present at an average person’s eye level. The thermostat in a convection system has no idea what
the temperatures are near the floor (these may be much lower), nor does it know the temperatures
near the ceiling (these may be much higher).
ILO North America recommends a purpose
infrared designed thermostat (such as a
black ball or black bulb thermostat) is
installed for optimal control and the highest
efficiency - see
Figure 10a
. These
thermostats are tuned to sense infrared
radiation in a room and not the air
temperature. A standard thermostat is an
adequate substitute if a black bulb
thermostat is unavailable.
Figure 10a – Black Bulb Thermostat
Independent scientific tests have shown the thermostat can be set approximately 3.5°F (1.8°C)
lower when using an infrared heating system to achieve the same level of perceived heating comfort.
In place of the typical 70°F (21°C) setting, the thermostat can be set to 66.5°F (19.2°C). It is this
lower temperature setting that is the primary energy saving when using IR heating.
With ILO’s far infrared heaters, the differences between floor and ceiling temperatures are so small
that the thermostat may be used at almost any convenient location. This freedom to choose makes
an ILO system an ideal candidate for using a plug-in utility power thermostat. Wherever the power
outlet is located, the thermostat may be used.
11. Using Your ILO Heating Panel
WARNING
– Do not cover the heating panel with any materials such as clothing, rugs, curtains,
towels, etc. These products are flammable and covering the heater prevents it from operating
correctly and safely. Covering the heating panel is a violation of the limited warranty.
1. After the heater is mounted on a wall or ceiling, plug the cord into the outlet.
2. Locate the main switch and switch to the ‘On’ position. There are no visible power lights or
indicators on the heater. It is possible the heating panel will make sounds as it heats up. This
is normal and is no cause for concern. It is due to the expansion of the metal frame.
3. After a short while, the heater surface will rise in temperature and start radiating energy.
4. Eventually it will reach approximately 200
°
F or 90
°
C.
5. To switch off the heater it is necessary to move the main switch to the ‘Off’ position.
6. After approximately 30 minutes, the heater will be at ambient temperature.
