TECHNICAL DESCRIPTION

Application
The device is designed to control the combined heating of boilers having two independent heaters powered by photovoltaic panels and mains power.
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.
Front panel
1 – LCD indication;
2 – “forward” change button;
3 – “back” change button;
4 – button to enter / exit programming mode.
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;
Settings
With buttons „↑” or „↓”scroll until the display shows the desired setting. Press button „√” to enter programming mode, then the setting value starts flashing. With buttons „↑” or „↓” you can make changes. To confirm the changes, press the button „√” again. Description| Indication| Range| Default settings| User settings
