Electric boiler FORWARD-14 EVAN NS-1669828

OpenTherm control Modbus RTU control ("smart home" integration) Automatic power stage control Heating control via air temperature sensor, adjustment range from 5 to 35°C Heat carrier temperature maintenance, adjustment range from 8 to 85°C Heating control via external thermostat Functionality: Automatic temperature control and maintenance Modes: Heating/Room/Outdoor Weather-dependent control via temperature curve in "Outdoor" mode Cascade operation (master / slave) Pump overrun control Connection of both DS18B20 digital sensors and industrial 4..20 mA current sensors (DTV-01-12) with a distance from the boiler of up to 100m Safety: Emergency self-resetting thermal switch Minimum pressure relay (protection against pressure drop) Reliability: Stainless steel block heating elements Increased relay service life due to large bulb Ability to connect a voltage stabilizer to protect the boiler electronics and electrical components Overheat protection: emergency self-resetting thermal switch High regulation accuracy due to the NTC temperature sensor built into the boiler bulb Optimal uniform heating Hot water supply: DHW water temperature control when connecting an indirect heating boiler, a three-way valve, and a 10 kOhm temperature sensor (EVAN AQUA DHW control module is recommended) Ability to maintain water temperature in the indirect heating boiler
