Output LED Lights

• Each of the MC Elite has a S.P.S.T. (N.O.) System output relay to be used to
activate a boiler, a cooling unit, or a pump. The relay is rated at 1 A (1/8 HP).
The relay operation is represented by the right most LED light.
• The middle LED (INCREASE) will always indicate that the signal is increasing
(opening).
• The left most LED (DECREASE) will always represent that the modulation
signal is decreasing (closing).
