How can remote control of the Sendo SMMC heat pump be achieved?

Remote control can be performed in 2 different ways:

1. By supplying a wired remote control that carries within the space, all the functions of the pump.
2. Using two cold contact switches to control:

a) On-Off of the pump and

(b) the cooling/heating mode rotation. They are connected according to the instructions in the technical manual of installation and use.
