A mode of operation is desired where field technicians can directly energize outputs on the control without needing to rely on the normal sequence of operations.
A new menu has been added under Commissioning called “Commissioning Mode” The following
outputs can be overridden while commissioning mode is active.
- Supply Fan Command (off/on) (Fan)
- Fan %Command (FanVFD)
- Compressor Stage Command 1 (C1)
- Compressor Stage Command 2 (C2)
- Compressor Stage Command 3 (C3)
- Compressor Stage Command 4 (C4)
- Condenser Fan 1 (CN-Fan)
- Condenser Fan 2 (CF2)
- Heating Stage Command 1 (H1)
- Heating Stage Command 2 (H2)
- Heating Stage Command 3 (H3)
- HotGas Reheat (off/on) (HGR)
- HotGas Reheat (modulating valve %) (HGR)
- Hot Gas Reheat Bleed Valve Command (Open/Closed)
- Economizer Damper % Command (Econ)
- Exhaust Fan VFD % Command (ExFanVFD)
- Exhaust Fan Command (off/on) (ExFan)
- Exhaust Damper % Command (EAD-O)
- Cancel ASCD Timers
Commissioning Mode Enable point is at top of the new menu.
- Commissioning Mode is active for 60 minutes unless the Extend Commissioning Time function is used.
- Commissioning Mode menu can be exited without impacting the functionality. This allows user to navigate menus to view temps/pressure/etc.
All Safeties can still override commissioning mode. Example: Cannot energize compressor 1 if HPS1 is in alarm
Supply Fan is required before allowing compressor and heat stage outputs.
Compressors being energized requires corresponding condenser fans to be energized.
