Accessory Control (Humidifiers, Dehumidifiers,
Ventilators)
If an external humidifier, dehumidifier or ventilator is installed, it
may require airflow from the HVAC system to function properly.
1. Make sure the installed 24 VAC thermostat is capable of
controlling the accessory or accessories.
2. Connect the appropriate accessory control wires to the
accessory devices from the thermostat (see thermostat
manual for connection and setup instructions).
3. If the thermostat is capable of providing a continuous fan call
(G signal) during accessory opertion: Make sure to connect
the thermostat G terminal to the G terminal on the indoor
unit. Setup thermostat to ensure G signal is energized during
accessory operation.

using the indoor unit push button menus or the CoolCloud
HVAC phone application.
5. Using the thermostat, independently test each accessory in
addition to the independently testing continuous fan mode.
Ramping Profiles
The variable-speed circulator offers four different ramping profiles.
These profiles may be used to enhance cooling performance and
increase comfort level. Select the desired ramping profile using the
CoolCloud phone application or the push button menus.
When used with communicating outdoor units the cooling profile
must be selected in the outdoor unit menus.
When used with non-communicating outdoor units the cooling
profiles must be selected in the indoor unit menus.
