HUMIDIFIER CONNECTION -- A 24vac bypass or fan
powered humidifier may be installed.
NOTE: Do Not Use a traditional humidistat to control humidifier
operation. If a humidifier is installed, let the Infinity Control
operate humidifier.
BYPASS HUMIDIFIERS -- A bypass humidifier should be
wired directly to the furnace or fan coil HUM and 24vac COM
terminals. The Infinity Control will automatically energize the
HUM output during a call for humidification.
FAN POWERED HUMIDIFIERS -- Most fan powered
humidifiers produce internal 24vac in order 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 relay coil to furnace or fan coil HUM
and COM terminals will allow the Infinity Control to
automatically energize the HUM output during a call for
humidification. The N.O. relay contacts ,,vill be used to energize
the humidifier. See fan powered humidifier installation
instructions for more details.
EQUIPMENT HAZARD
Failure to follow this caution may result in equipment
damage. Do not apply 24vac fan powered humidifier
(with internal power supply) direct to indoor unit
HUM and COM terminals.
