Solar controller SR868C8Q

SR868C8Q controller for single-circuit system with a measurement function generated heat

Solar thermal controller is a required element of solar systems with forced circulation of coolant. It is designed to control the heating process from the sun and monitor the status of the solar system. The controller receives information from the temperature sensors (one of which is installed at the outlet of the solar collector) and regulates the operation of the circulation pump. Efficacy and safety of solar largely depend on the controller: correctly embedded algorithms of solar and security elements

difference SR868S8 SR868S8Q and controllers is the controller that it is possible SR 868S8Q registering +2 temperatures collector. field and 3 -x temperature of storage, and also added the following functions:
- control of the pump performance, depending on the temperature difference and the duration of heating;
- measurement of thermal energy from the call projector of;
- coolant flow measurement;
- selection of the type of coolant (water, propylene glycol, tifokor);
- temperature measurement in the reservoir even if the sensor is mounted at a distance from the outlet manifold;
- The "weekend"
- These features allow you to enhance system performance and provide a high level of security ..
