Activate the Accelerated Cooling/Heating FunctionUpdated 3 days ago

This article explains how to activate the Accelerated Cooling and Heating function for Vertex Ducted Central Split (DYC-18) systems. 

This function improves the dehumidification capacity in Cooling mode and increases the unit capacity.  

The DIP switches SW3-3 and SW3-4 are set to the "Off" position by default. If DIP switch SW3-3 is set to the "On" position, the target coil temperature will reduce in Cooling mode. If DIP switch SW3-4 is set to the "On" position, the target coil temperature will increase in Heating mode.
