TECHNICAL DESCRIPTION
1. Application
The device is designed to control the combined heating of boilers having two
independent heaters powered by photovoltaic panels and mains power.
2. How it works
Maintains the water temperature in the boiler Tb by turning the heating on or
off according to the set point and hysteresis.
It has a built-in weekly programmer with two programs to allow the heater to
operate on mains power. The temperature to which the boiler is heated from the
mains is determined by a separate task.
It monitors the current and voltage of the photovoltaic panel and measures the
instantaneous power consumed.
When the “MPPT|” mode is on, the maximum power point from the panel is
monitored according to the momentary sunlight. In this way, efficient use of the
panel is achieved in low sunlight. In this mode, the set hysteresis does not affect the
operation of the thermoregulator, power is always supplied to the heater at a
temperature lower than the Tb set.
Operation without “MPPT”
At a temperature of the boiler Tb lower than the Tb set-hys, the heating is
switched on, the condition continues until the Tb set is reached.

In the initial state, the display shows the following parameters:
- Up –panel voltage;
- Тb–current boiler temperature;
- P–panel power;
- AC ON –mains heater is ON;
- AC OFF –mains heater is OFF;
