Note: The de-humidification sequence has a typo in the IOM (WSHP-SVG02E-EN, page 11-12). The correct sequence is below with changed items in bold.
To avoid sub-cooling the space if the reheat is not sized properly or during certain system conditions, a low limit temp is established to exit dehumidification mode. The low limit is the occupied cooling setpoint-1.5F in all occupancy modes. This enables extended dehumidification during unoccupied and standby modes which allows sub-cooling the space to the default OCCUPIED setpoint - 1.5F. If the zone temperature reaches the low limit the DX cooling and reheat will be turned off. The zone temperature must then rise 1.5 F above the low limit before the DX cooling and reheat are allowed to operate again.
