Heat Controller DMH36TB-1 Manuel D’Utilisation

1. Check that all tubing and wiring have been properly connected.

2. Check that the gas and liquid side service valves are fully open.

Remove the battery cover by pulling it according
to the arrow direction.
Insert new batteries making sure that the (+) and
(–) of battery are installed correctly.

position.

:

• Use 2 AAA(1.5volt) batteries. Do not use

rechargeable batteries.

• Remove the batteries from the remote control if

the system is not going to be used for a long
time.

Operate all indoor units for 15~20 minutes, then
check the system refrigerant charge:
1.Measure the pressure of one of the gas side

service valves.

2. Measure the temperature of the intake and

discharge of air.

3. Ensure the difference between the intake

temperature and the discharge is more than
8°C(14.4°F).

4. For reference, the gas side pressure of

optimum condition is as below.(Cooling)

: If the actual pressure are higher than

shown, the system is most likely over-charged, and
charge should be removed. If the actual pressure are
lower than shown, the system is most likely
undercharged, and charge should be added.

: For maximum product life and efficiency

this unit has been designed,  in the heating mode, to
lock-out at outdoor temperatures below  26-29°F.
At outdoor temperatures below 26-29°F. another means
of heating  the conditioned space must be provided.
