4. Solar controllers
4.1. STDC controller
It is a compact differential temperature controller designed for simple solar systems. The basic hydraulic schemes include: a solar collector connected to a
water heater; and solar collector connected to a swimming pool.
4.2. MTDC controller
This controller is designed for more complex solar systems. It has 20 hydraulic schemes, as well as addition features, like east-west location of the collectors,
a function to overload the water heaters, as well as functions to cooperate with heat exchanger and a swimming pool.
5. Pump group installation
Thermal insulated housing - EEP
Dimensions 277 x 425 x 150 mm.
Front part of the housing covers the whole pump besides the
safety valve. Mounting bracket for the 22 mm pipe is located
inside. There is a hole in the housing used to control the
flow state without the need to dismantle the housing. The
back part of the housing is mounted on a steel plate, which
allows for mounting of the unit on the walls or directly on
the water tank.
Model with air separator
Air separator is a device that separates the air (small air bubbles)
from the glycol fluid. The air accumulates in the top of the
separator and is removed by manually by valve during solar
installation's operation. The venting is done by turning the valve
by 360° repeatedly until the air is completely removed from
the separator.
The metal back plate enhances the rigidity of the whole unit and eases
the installation of the device on the wall or on the water tank directly.
The two holes located on the back of the device allows for easy
installation without the need of dismantling the whole unit.
WARNING - RISK OF BURNS:
While venting the unit, the solar fluid - glycol,
might leak. It is recommended to put tube on the
tip of the venting valve to avoid the possible burns.
