DOMESTIC HOT WATER PERFORMANCES
HEATMASTER ® SETTING INSTRUCTIONS
Description
The HeatMaster ® 201 range is equipped with an electronic
controller (MCBA) which controls the burner (start-up, safety, and
modulation) and allows the controller to be adapted to the selected
application.
The MCBA system includes a controller with 3 levels for setting the
parameters: manufacturer, installer, and user. It includes 3
temperature sensors located in the primary and secondary circuits.
There are two operating modes:
1. Heating mode
The T° is set by the user in the range 60 to 90°C.
• Differential “ON” starts the burner.
• Differential “OFF” stops the burner.
• PI controller (Proportional Integral) in “Heating” mode.
• The controller compares the primary temperature with the
setting and the module.
The room thermostat detects the demand for heat.
2. Hot water mode (with priority to the hot water)
The T° is set by the user in the range 60 to 90°C.
The sensor located in the secondary tank detects the demand for
hot water.
As soon as the draw-off is detected, the controller goes to “demand
for hot water” mode:
• Differential “ON” starts the burner.
• Differential “OFF” stops the burner.
• PI controller (Proportional Integral) in “Hot water” mode.
• The controller compares the primary temperature with the
setting and the module.
• The charging pump starts up.
• The heating circulator pump is no longer supplied.
• The burner starts and the controller controls the modulation
based on the primary pump.
Parameters accessible by the user
1. “Hot water” temperature, which can be set to 20 - 90°C.
2. Hot water mode ON/OFF.
3. Heating mode: ON/OFF.
4. “Heating” temperature, which can be set to 60 - 90°C.
Parameters accessible for “service”
Main basic characteristics:
- Hot water priority active.
- Demand for heat detected by the room thermostat.
- Only one heating circuit.
An access code is required to access “Service” parameters.
