Solar and heating controllers
Solar thermal systems are operated and controlled by solar controllers. RESOL differential temperature controllers are used in solar, heating and air-conditioning systems to initiate switching processes depending on thermal, hydraulic and environmental conditions. Apart from these basic functions, RESOL controllers offer a variety of options and functions for the optimum use of individual solar and heating systems.

Datalogger & VBus®-Accessories
Data communication between different components takes place via the RESOL VBus®. The controllers are therefore able to communicate with additional modules, allowing the system to be analysed and adapted to the individual consumer and system.
Pump stations & Accessories
Pump stations offer solutions for the efficient use of a system through harmonised components. They contain all units necessary for the operation of a solar system. Installation and initial operation of the stations are easy, because the components are already pre-assembled and ready to plug in.

Thermostats, measuring instruments & calorimeters
Thermostats, measuring instruments and calorimeters are important devices for the installer as well as for the end user. A thermostat is an electronic controller which compares the temperature detected by the sensor to the preset value and controls it using actuators, such as pumps and valves, to achieve that value. The purpose of variable controllers for circulation systems is to make warm water available without delay. Furthermore, the RESOL product range includes components such as measuring instruments and calorimeters which can be used separately.
Sensors are used to detect certain quantities such as temperature and irradiation. Platinum sensors, which change their electrical resistance proportionally to the temperature, are used for temperature measurements. The sensor type is indicated by the third letter “P”, for example: FKP or FRP. FK designates the sensor of the heat source (e.g. collector sensor) and FR the reference sensor (e.g. storage sensor). These sensor types have the same electrical features. They differ only in the connecting cable.
Valves are used to control fluid flow. In hydraulic systems, different valves are used in order to run parts of the system separately or to switch on or off particular parts as required. 2-port valves allow or stop flow rates. Changeover valves are used to distribute and redirect flow rates. In order to avoid noise pollution and system damage, there is no back stroke.
Accessories such as remote controls, auxiliary relays or additional modules are used to add further functions to the solar or heating system. By means of a heating circuit module, an additional heating circuit can be controlled, other accessories enable the connection of further loads or the remote adjustment of the system. Spare parts for our appliances ensure a quick and professional maintenance and repair.
