SDC7-21WM Wall mounting 1x: mixing valve + pump; pump

Microprocessor controller with fixed hard- and software. Configuration with 15 sets of parameters. Remote access with App and Gateway.

For all Heating and District Heating applications with:

• direct heating circuit and/or mixed heating circuit(s)
• boiler burner
• domestic hot water
• heat exchanger valve

Control software: the software application can be selected, by keying in a planttype code, and can be adjusted with parameters; or use no code number and configure the application with the parametersets only

Bus system description: Bus sytem for max. 5 SMILE controllers, and 3 setpoint units per controller; max. buslength 100 m; the controller can also be used as stand-alone controller.

Hardware outputs: all outputs are relay outputs with a maximum contact load of 2A 250V

• the standard relay outputs are for pumps and valves, and are controlled from the selected application; mixing valves need 2 output relays
• the function for the additional relay outputs can be set with parameters

Applicable sensor types: NTC 20 kohm

Additional description:One of the hardware inputs is for a pulse contact. This can be used for example for counting running hours. With parametersettings the amount of counted pulses can be used for switching pumps or boilers
