Trane RLY1770 Fan Time Delay Relay Sequencer

The Trane RLY1770 is a Fan Time Delay Relay Sequencer is a unique part of electronics that is used to manage the fan of a central HVAC system.It features a time delay function that ensures fans in the system start and stop at different times to enhance the performance of the HVAC system.The use of a sequenced start and stop also reduces the amount of current drawn at any one time, reduces the stress on the powerem. It also prevents the simultaneous startup of electrical appliances which is dangerous as it may overload circuits and hence makes the system to run smoothly. Further, the staggered shutdown helps in equalizing temperature within the conditioned space and thereby improving comfort and possibly energy efficiency.
