Aspen Fan Speed Controller - Heat Pump

Aspen Fan Speed Controller - Heat Pump model

The Aspen Fan Speed Controller is designed to regulate the condensing pressure of your air conditioner in “cooling” mode in case of outdoor working temperatures below +21°C with a minimum of –5°C.

The goal is to obtain a condensing pressure between 230 psig and 245 psig for installations running on R407C with a positive difference of +8% towards installations running on R410a.

The heat pump mode has terminals to be connected parallel to the 4-way valve in 'heating' mode. This connection type allows the controller know the difference between 'cooling mode' and 'heating mode' and to adapt regulation accordingly.
