water heater thermostat

electric water heater thermostat (thermostat controller, radiator thermostat, touch-screen thermostat, room programmable thermostat, digital thermostat) Introduction TheE51... is used for 2-position control with on/off output for the control the temperature by means of an NTC sensor placed externally or internally in the thermostat. The thermostat acquires the actual temperature with its built-in sensor or floor sensor, and the heating contact will close when the room temperature falls below the selected setpoint. Application For the control of warm-water( floor) heating systems and direct electric heating systems used in Commercial buildings, Residential buildings, Light industrial buildings... Features 7-day programmable function for energy-saving operation On/off control output for heating device Symbol indicator when heating is on Mechanical switch key for power supply Temperature limitation function for protecting the floor 7-day time maintenance in the event of a power failure Large size LCD display for better readout “Key-lock” function for protecting the setted parameters (especially suitable for Public places) Technical dataVoltage: AC230V/220V Power consumption: 2W Setting range: 5 50 Celsius (factory setting: 35 90 Celsius) Limitation range:5 60 Celsius (factory setting: 35 Celsius)Ambient temperature: -5 +50 Celsius Switching differential: ±0.5K Protective housing: IP20 Housing material: self-extinguishing PC Floor sensor: rubber-thermoplastic NTC sensor, cable length is 3mSelection Table ModelCurrentApplicationE51.7133ABuilt-in&floor sensor,floor limit sensor,weekly programmeE51.7233ABuilt-in&floor sensor,floor limit sensor,weekly programme.A potential-free outputE51.71616ABuilt-in&floor sensor,floor limit sensor,weekly programme Pls contact us for more detail information.
