ELECTRICAL CONNECTIONS
All electrical connections must conform to local
and national codes.
CAUTION! For Supply Connections, use wires
suitable for at least 194°F (90°C).
A single phase motor is used to drive the ThermaQuiet
blower on 115 – 120 V. 60 Hz. Since current drain is very
small, wiring codes for short circuit protection only will
apply. The motor is connected to a circuit board that has
sensors for both air and water temperature.
Diagram 1: Single Fan Motor - DL65-WM
Electrical Connections are to be made to all units following
the diagrams below. Choose the diagram that best suits
your application.
Since the blower runs on all ThermaQuiet models only
when the system circulator pumps hot water through
the unit, simply connect it to the 115V line. If water
temperature sensor reads adequate temperature (greater
than 79°F) the blower then starts after a short warm-up
and stops a few minutes after the circulator shuts off.
Boost
Momentary pressing boost/cool will result in temperature
control being abandoned for 20 minutes and will enable a
higher output setting not normally accessed in comfort
settings. Note, this also depends on water temperature
being high enough. System will revert to temperature
control after this time.
Summer Cooling
In summer, it is desirable to initiate air movement in warm
conditions. If the On/Off AND the Boost/Cooling buttons are
depressed simultaneously for more than one second, then
the water temperature will be ignored, and the airfl ow will
ramp up to boost levels until the ThermaQuiet is switched off.
Request for Heat LED
This will fl ash Blue if heating is requested and the water
temperature is less than 79°F.
USER ACCESS
On/Off
When on/off button is pressed and held for more than
one second, if water temperature is greater than 79°F,
and if room temperature is below the comfort setting,
ThermaQuiet begins operation.
Comfort Setting
When the unit is on, if the on/off button is depressed less
than half a second the selected setting is incremented
upwards by approximately 3°F. Repeated pressing will
increment to the highest setting and will scroll back to
lowest again, etc.
LED Indicators
The setting LED’s from left to right represent 65, 68, 72,
75°F respectively target temperatures.
Please note that these levels are actually compensated levels,
and for instance if 68°F is selected, this is compared to the
compensated temperature measured at low level which is the
predicted temperature at occupant level. The selected LED will
fl ash slowly while the temperature is being raised. When the
temperature reaches setpoint, the LED will turn solid.
