After the room is properly set up and balanced, you should not need to change
the relay settings. Changing the settings after the room is set up can affect the
ventilation balance in the room. If you need to change settings after the room is
set up, you should change the Power Block settings. For more information, read
Programming Power Block settings on page 31.
If the Power Block is in empty room mode:
Cooling equipment – no relay settings are available and equipment does not
operate.
Heating equipment – all settings are available. Equipment operates only if needed
to keep the temperature at or above the set point.
Use the Heating and cooling elements worksheet on page 88 when programming
relays.
