Coupling harness for HVAC mini-split system
View Patent ↗A coupling harness useful with a HVAC mini-split system includes a first interface connected to a thermistor, a second interface connected to a condensate overflow sensor and a control device interface connected to a HVAC electronic control device. The first and second interfaces can notify the control device interface of the existence of an alarm condition of the thermistor and condensate overflow sensor, respectively. The control device interface can actuate the HVAC electronic control device in response to such notifications that an alarm condition exists for the thermistor or condensate overflow sensor.
1. A method of providing alarm signals to a HVAC mini-split system having a thermistor, a condensate overflow sensor and a HVAC electronic control device, said system controlling a compressor, the method comprising:
engaging a single, unitary, removable, releasable, self-contained, alarm coupling harness with the HVAC mini-split system, the alarm coupling harness having at least first, second, and third ends, said first end having a first electrically-coupled connector electrically connecting with the thermistor, said second end having a second electrically-coupled connector electrically connecting with the condensate overflow sensor, and said third end having a third electrically-coupled connector electrically connecting with the HVAC electronic device
at least one among the first and second interfaces directing a signal to the third connector when an alarm condition exists in the thermistor and/or condensate overflow sensor, respectively;
in response to a signal received from either the first or second connectors, the third connector notifying the HVAC electronic control device that an alarm condition exists; and
stopping the operation of the compressor.
