Automatic heat source selection and electronic temperature control of heat exchanger outlet for pool regulation systems ECOPOOL can be used for pool heating where managing the commutation between two different heat sources in an automatic way is necessary, for instance solar thermal and gas boiler. ECOPOOL is available in following diameters DN20, DN25 e DN32. Other diameters are available on request. DESCRIPTION The kit is composed by n. 2-way motorised valves with different functions: deviating valve (1) gives the priority to an heat source (eg. solar thermal) when the temperature is enough to warm the pool. If this does not occur it deviates and connects the second heat source (eg. boiler) in an automatic way. In order to activate the working process, the actuator must be connected to a thermostat (not included) that can detect the temperature of the accumulation technical water of the priority heat source. Electronic regulation of the inlet temperature to the pool; Possibility of remote control thanks to the RS485 serial connection with Modbus-RTU protocol.. Automatic switching between two different energetic sources according to the available temperature; The modulating valve (2) keeps constant and precise temperature value set on the plated exchanger output for the benefit of the comfort and of the energy saving. Temperature setting can be made locally, thanks to the User interface (keyboard and display),r remotely thanks to Modbus-RTU serial connection.
