List Of System Operation Variants - Compit SOLARCOMP 911 Installation And Operating Instructions Manual

Introduction
SOLARCOMP 911 controller has been designed for control of thermal solar heating
systems. Basic features of the controller include:
1. Special purpose graphic display – a special-purpose display makes the operation
of the controller easy. It helps to identify the system variant used and system
parameters.
2. Heat meter – the controller calculates the amount of heat obtained form the solar
panel.
3. Smooth pump control – the controller provides smooth control of the pump
loading the tank, which allows for economic use of solar energy (the energy can be
obtained form the solar panel even in dull weather).
4. Solar panel heat discharge – the controller offers a special HOLIDAY MODE
which protects the system from overheating when hot water is not used.
5. Regular DHW tank sterilization – the tank is disinfected every week to destroy
bacteria in water.
6. Solar panel frost protection – the controller protects solar fluid from freezing by
activating the pump when the panel temperature drops below the set limit.
7. Tank frost protection – the controller switches on the heating coil or another heat
source when the tank temperature drops below 4°C.
8. Protective functions – the controller uses control algorithms for the solar panel
and tank protection. This protects the panel from overheating (and consequently
allows for stopping the tank loading) or protects the tank from overheating.
9. Extended system control –an additional output provided enables the device to
control extended systems when two extra sensors are connected.
