As shown in the diagram
-Can connect more than one room thermostat, in parallel
Boiler operation of the room thermostat
-With the electronic table and the room thermostat can
operate in three different independent functions:
1. Boiler for heating.
2. Boiler for hot water production.
3. For heating and hot water simultaneously.
Operation of the room thermostat
-The top switch activate the operation of hot water production.
-The bottom switch activate the operation of heating. (With rotary switch, select the room temperature
you wish for).
-Activating both switches we have heating and hot water simultaneously.
Faults indication and solutions
-[Å 1] Sensor problem: short- circuit sensor
cut sensor
Unable temperature sensor to read
[ Possible exit of the sensor from its position]
After you identify and solve the problem activate again the boiler
-[when the burner stops]: Gearing of the burner.
After we identify and solve the problem, we activate the burner from the red switch which is located on
the burner.
Notice: For any problem of the boiler you must contact your certified technician. Do not interfere other
people.

Installation instructors
Page 5 / 5
For the installation of Master boiler the following hardware need to be connected:
1. Expansion tank (24lt) in the heating circuit or bigger than that if it is required by the installation.
2. Safety valve 1/2" 3BAR.
3. Automatic air vent of 2 pieces or more depending on the installation.
4. Filling valve ½” with manometer.
5. Magnesium anode for protection against salt.
6. Blackflow prevender in hot water circuit.
7. Expansion tank (8lt) in hot sanitary water circuit.
8. Pressure reducer in hot sanitary water circuit since we have increased pressure in our network.
Master Bïiler connection
1. The hydraylic connection of the boiler is based on a project and you can find it on this booklet as
well as at back side of the boiler.
2. You should avoid connecting the boiler tuborama with the hot water circuit.
3. The electrical cinnection is based on the diagram of the manual.
Boiler settings
1. The pressure of the heating circuit should be regulated by 1-1,5 BAR.
2. For proper and economical operation the setting of the burner should be done by a licensed
technician.
3. The temperature at which the burner stops is preset.
4. The temperature at which the circulator stops is preset.
Boiler maintenance
1. It is necessary the annual cleaning of the boiler as well as cleaning and adjusting the burner by a
licensed burner technician.
2. It is also necessary a periodic cleaning of the heat exchanger (coil) to prevent icing salts.
Otherwise, alternator will be blocked. The cleaning is done by special liquids that you can find in the
market. Time of regular cleaning depends on the hardness of the water and the frequency of use of
the boiler.
Room thermostat installation
1. Ôhermostat should be placed in the room that concerns us more the changes in temperature.
2. Thermostat should not be placed near a radiator, in front of a wall that just behind a radiator is
located or in a wall that tubes exists.
3. Also not to be placed near a window or a balcony door.
