These are the instructions I followed last month:
Soft Bypass
At times, it is necessary to bypass the energy management functions of the
system. To do this, press and hold the F/C button on the WDDC for 3
seconds and you will see bp (bypass) on the screen. The unit sends a
message to the RCU changing the settings so that it functions as a normal
thermostat with no energy management functions for 48 hours.
If it works, you'll need to do this every other day. I just do it every morning to make sure it still is in bypass mode.
