I have a small problem, the air handling unit I have installed in the boiler room has a "venting mode" option that can be activated by a simple contactor. Short-circuiting two wires (connected to the corresponding inputs on the printed circuit board in the air handling unit) causes the air handling unit to go into ventilation mode regardless of the set schedule, opening it causes the air handling unit to return to the weekly programme. The whole problem is that the air handling unit is located in the boiler room and the switch which would be responsible for the conclusion of these contacts I wanted to place in the bathroom, and I did not physically run the cable under the plaster. I was thinking of a radio-controlled relay. For example, when I enter the bathroom, I switch on the button and it sends a radio signal to the relay in the boiler room to short-circuit the contacts of the control panel and switch on the ventilation mode; when I leave the bathroom, I switch off the button and the relay in the boiler room opens the contacts. I think it would be nice to delay the contact opening so that the control panel remains in ventilating mode for another 5 minutes after I turn off the button in the bathroom. Is there one device that will solve my problem? Or does it need to be done with a couple of devices?
I generally posted on the forum because I thought someone would specifically give the name of the component or components possibly how to do it most simply, you think I didn't type that in googles? cool
