R221 is a controller with ModBus communication, to control heating and cooling.
R221 has 3 inputs for different types of sensors and 3 digital 24V outputs and 1 analog 0-10V output.
The controllers in and outputs can be customized directly with the controllers buttons and display.
The controllers inputs can be adapted for different types of sensors such as condensation sensors, temperature sensors or an external contact for forcing, or operation mode override functions.
The output functions such as limit values, sequences and cooling/heating functions can be adapted to control up to 4 steps in sequence.
