How your programmable thermostat works

When the thermostat is in the AUTO mode, it will operate according to the
times and temperatures that have been programmed. The user can select
from 6 dierent programs per day - each with a time and a temperature.

There is no OFF time, only a higher and a lower temperature.

If the user wants the thermostat to be OFF at a certain time, set the
temperature for this time to be low. The thermostat will turn ON if the room
temperature is lower than the setpoint for the current period.

Example: If P1 is set to be 21˚C at 6am, and if P2 is set to be 10˚C at 8am, the
thermostat will look for the temperature to be 21˚C between 6am and 8am.

3. Mounting

The mounting height should be 1.5 metres above the oor level.

The thermostat should be wall mounted in the room where the heating is to
be controlled.

The place of installation should be chosen so that the sensor can measure the
room temperature as accurately as possible.

Choose the mounting location to prevent direct exposure to sunlight or other
heating / cooling sources when mounted.

The unit can be tted to:

1. Directly on walls.

2. Table mounting with stand provided.
