Remote Thermostat Control – Cooling Mode
1. Set wall thermostat to “Cool Mode.”
2. Set wall thermostat at desired setting.
3. Select AUTO/FAN operation.
4. Using the “System” key pad, depress “Fan” key until desired speed lamp
is illuminated.
NOTE:
When Dynaline
™
3 is controlled by a wall thermostat, the sequence
of operation is the same as with built-in thermostat control; however,
the temperature setting and system functions are selected at the
wall thermostat.
NOTE:
On initial start-up, the compressor will not be energized for five (5)
minutes even though the system functions have been properly selected. This
is to protect the compressor. This feature can be overridden by
pressing the “System” and “Cooler” pads at the same time.
NOTE:
Whenever the outside temperature is below 65°F and the
humidity is high, frost could form on the evaporator coil during extended
cooling operation. To eliminate frost formation, a de-ice switch in the com-
pressor circuit will sense a frost condition and open the compressor circuit.
Upon temperature rise, the switch will close and the compressor will again
come on provided that the thermostat is still calling for cooling.
NOTE:
Dynaline 3 has a built-in 5-minute delay between compressor cycles.
Anytime the compressor cycle is interrupted either manually, through the
thermostat, a power interruption, etc., the compressor will not restart for 5
minutes. Also, the A/C compressor, once started, will run for 1 minute even
if the cooling mode is switched off.
Heat Mode or Cooling Mode
1. At times it may be desirable to reduce the operating sound level. This
is possible by selecting “Low” fan speed. (See
Figure 31
.)
2. Circulation of room air with no heat or cooling may be obtained if
desired. To accomplish this, select the “Fan Only” position on the
“System” key pad.
3. Operate unit with the fresh air vent in the closed position except when
introduction of outside air into the room is desired.
4. Clean filter as part of regular maintenance.
5. Have regular professional maintenance to clean burners and ensure
proper performance.
6. Keep windows and doors closed. Conditioned air escapes when they
are open.
7. Operate at high fan speed during extremely hot or cold weather.
8. Keep outdoor condenser coil clean.
9. Turn the unit off during vacations or extended absences.
