HEATMASTER CONTROL SETTINGS

Description

The 71/101 series is fitted with an electronic controller (MCBA) which controls burner operation (ignition, safety and modulation), and provides facilities to adapt the controller to the desired application.

The MCBA has three levels of settings : manufacturer, installer and user. There are three temperature detectors located in the primary and secondary circuits.

It provides two operating modes.

1. Heating mode

Temperature set by the user at between 60 and 90 °C.

Differential “ON”, burner starts.

Differential “OFF”, burner stops.

PI (Proportionnel Integral) regulator in “heating” mode.

The regulator compares the primary temperature with the setting and modulates.

The room thermostat detects the heating demand

2.Hot water mode (with hot water priority)

The detector located in the secondary tank detects the hot water demand.

When a draw-off is detected the controller goes to “hot water demand” mode:

The primary shunt pump starts.

The heating pump switches off.

The burner starts and the controller uses the data from the primary detector to control modulation.

User-accessible parameters

1.“Hot water” setting adjustable from 20 to 90 °C.

2.“Hot water” mode: ON/OFF.

3.“Heating” mode: ON/OFF.

4.“Heating” setting adjustable from 60 to 90 °C.

Parameters accessible in servicing

Main default settings:

-Hot water priority active.

-Heating demand detection by room thermostat.

-A single heating circuit.

An access code is required for “service” access.
