Complex fan coil unit wiring diagram - Differential pressure (dp) switches display fan motor fame by way of sensing the distinction in pressure among the supply and discharge aspects of the fan. This is done by using penetrating the duct work and installing pick-up tubes on each facets of the fan. The tubing is connected to a mechanical switch that has a unmarried adjustable trip factor. Whilst a trade in the differential pressure between the pick out-up tubes is detected, the switch opens or closes consequently. In a consistent extent fan motor, approximately 60 of the power ate up is used to transport the air, leaving forty or less of the strength fed on to show the motor. While the fan motor has a mechanical failure or belt breakage the motor amperage drops more or less 60.

I am looking to upgrade to a brand new line voltage thermostat. The brand new thermostat has many greater connections, together with 3 fan speeds. My modern system has a manual fan turn on the wall so all i need the thermostat to do is allow strength to go with the flow to the fan coil unit. Current switches screen fan motor reputation through reading the amperage in the conductor imparting the motor. A mechanical failure within the motor reasons a drop in amperage that is right away detected by using the contemporary switch, which sends an alert to the manipulate system. Modern switches offer the most reliable and price powerful manner to screen wonderful proof of flow for fan automobiles in fan coil units (fcus).

This diagram tries to show how the gadget is stressed out and a proposed new wiring. I endorse this because i have tried attaching the heat and cool and neutral from the new thermostat to the r, and the black to the black. The white twine is capped at the thermostat and junction box ends, however i am offering to use that as the impartial connection on the thermostat and add it to the w to w present day connection within the junction field. Any recommendation on whether this will work?. This site makes use of cookies to supply our services and to show you relevant advertisements and task listings.
