Variable Speed Fan is a configuration that appears when the Pelican thermostat is wired to a Pelican PEARL economizer controller.
This configuration can be found in the Pelican Web-App > Admin > Thermostat Configuration > ‘select any thermostat‘ > Variable Speed Fan.
Configuration options and meanings:
The available number of configuration options, under Variable Speed Fan, adjusts based on how many stages of heating and/or cooling the thermostat is configured to control. The configuration for each fan speed is in percentages from 0% to 100%, where 0% equals a 0 Vdc output from (A2) and the fan will be OFF, while 100% equals a 10 Vdc output from (A2) and the fan will be at full speed.
Cool Fan Speed – Stage 1: This tells the PEARL what the fan speed should be when 1st stage cooling is enabled.
Cool Fan Speed – Stage 2: This tells the PEARL what the fan speed should be when 2nd stage cooling is enabled.
Heat Fan Speed – Stage 1: This tells the PEARL what the fan speed should be when 1st stage heating is enabled.
Heat Fan Speed – Stage 2: This tells the PEARL what the fan speed should be when 2nd stage heating is enabled.
Ventilation Fan Speed: This tells the PEARL what the fan speed should be when only the fan is enabled.
