the monitor to make sure the mode is changing as intended.

This function is commonly used when the blower is switched off elsewhere, such as by a building automation system, which usually incorporates a volt free contact to mute the alarm. When there is no automation system and the blower control is only a two-position switch in the room or on the hood, there must be a separate dry contact from the switch. The reason for this is the night setback function essentially switches its own voltage — one of the terminals on input 1 has the supply voltage on it (15VDC), this is then switched back into the other terminal to activate setback. If voltage from the blower switch is sent into input 1, the relay won’t function as intended. 4. “Link” power This approach involves wiring the monitor so when the power to an external source (such as the hood light) is shut off, the monitor powers off as well. This can be done by wiring the outlet that powers the monitor to lose power whenever the light loses power (kind of how a TV, DVD player, etc., all shut off when turning off the community surge protector/power strip). The monitor will remember its calibration when power is restored.
