The controller for the solar system SR81Q

The controllers are designed to meet the challenges of monitoring and control of solar systems for different purposes, maintain business continuity and maximize system performance. It can be used to design solar any complexity.

For solar control circuit of the closed type (indirect heating) and Tan control in the tank. Few maintain the water temperature regimes. An improved version SR868C8Q, there is the possibility of registering a 2-field and temperature of the collector 3 -x temperature of storage, and also added the following functions:

control pump performance, depending on the temperature difference and the duration of heating;
thermal power measurement coming from the reservoir;
measuring coolant flow rate;.
temperature measurement in the reservoir even if the sensor is mounted at a distance from the outlet manifold
These features can improve system performance and provide a high level security.

SR868C9 controller allows separate power part set (power and temperature sensors) and display controls. This allows to place the contact-force portion of the controller in the most appropriate place in terms of installation, service, control logic or switching between system components (e.g., boiler or furnace), and the display in the most convenient place for the user (Hall, bathroom, bedroom).
