Humidifier Connections
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 System Control operate humidifier.
4.6.1.
Bypass Humidifier
A bypass humidifier should be wired directly to the furnace or fan coil HUM and
24VAC COM terminals. The Infinity System Control will automatically energize
the HUM output during a call for humidification.
4.6.2.
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 System 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.
5. Commissioning
This section addresses initial power up (or commissioning) of a new Infinity
System Control. The control will communicate and identify all components in the
Infinity System. The following is a typical example for a communicating
variable--speed furnace / fan coil with a 2--stage air--conditioner / heat pump
(including HYBRID HEAT
r
dual fuel system). The process may vary for other
types of systems. See the Infinity System HVAC equipment Installation Instructions
for more details, as provided.
