Humidifier Connection

A 24VAC bypass or fan powered humidifier may be installed.

NOTE

:

Do Not Use

a traditional humidistat to control humidi-

fier operation. If a humidifier is installed, let the Observer®
Control operate humidifier.

Bypass Humidifiers

A bypass humidifier is normally wired directly to the furnace
or fan coil HUM and 24VAC COM terminals. The Observer®
Control will automatically energize the HUM output during a
call for humidification. See the humidifier installation instruc-
tions for the proper wiring procedure for each particular hu-
midifier.

Fan Powered Humidifiers

Most fan powered humidifiers produce internal 24VAC in or-
der to energize upon a switch or contact closure. For this
application, a 24VAC N.O. Isolation Relay (DPST)

MUST

be

used to prevent mixing the internal humidifier power with the
indoor equipment transformer. Applying 24VAC isolation re-
lay coil to furnace or fan coil HUM and COM terminals will
allow the Observer® Control to automatically energize the
HUM output during a call for humidification. The N.O. relay
contacts will be used to energize the humidifier. See fan
powered humidifier installation instructions for more details.
