MENU J – FACTORY SETTINGS (factory level) continued
Reheat – The type of reheat used. Choices are:
None - No reheat installed.
One - A single stage of reheat.
1-Elect - A single stage of reheat but used only in dehumidification mode.
HW Valve - (Not shown on IRDX Model). Hot Water valve used for heating. A
discharge air temperature sensor must be installed to select this mode.
Two - (Not shown on IRDX Model or MiniDAP). Two stages of reheat.
Three - (Not shown on IRDX Model or MiniDAP). Three stages of reheat.
3-Elect - (Not shown on IRDX Model or MiniDAP). Three stages of reheat but used
only in dehumidification mode.
HGRH - Hot Gas valve is modulated for reheat during dehumidification.
HGRH+1 – Like the Hot Gas mode but has a second stage of reheat.
HGRH+SCR – Like HGRH mode but also uses SCR to modulate reheat to
maintain temperature.
Enable Rotation: (Only displayed when there is more than one stage of reheat.
Default setting is rotation enabled.
Lead Reheat – (Only displayed when rotation is enabled) indicates the current
lead reheat stage. You can also manually change which one is the lead.
Enable SCR Y4: This enables the SCR modulated reheat. This reheat mode is
enabled automatically when the cooling mode is set to the precise selection.
SCR Band or HGRH
mode is set). This setting determines how far below set point minus dead band
temperature can drop until the SCR modulation will reach 100%. Range of
adjustment is 1 to 20°F with a default setting of 1°F.
