Test Mode can be accessed several ways:
— Thermostat inputs:
• Apply a Y + G request within 3 seconds after
power-up for 2 seconds.
• Next, remove the Y + G request and apply W
request within 10 seconds.
— EnviraCOM™ command
— The G signal enables the circulator in Test Mode.
If a G request is present, the circulator is con-
trolled as required by the heating or cooling
sequence. If the G request is removed, the circu-
lator turns off during the heating or cooling
sequence. If there is no other thermostat request
present, a G request causes the circulator to be
energized. The circulator will energize during a
heating cycle if the limit switch opens, regardless
of the G signal.
If there is a failure during Test Mode:
• An error code flashes indicating the failure. See
Table 11 on page 20.
• An EnviraCOM™ alarm is active and sent on
the bus. See Table 13 on page 22.
Test Mode is exited after any of the following conditions:
— Three minutes of operation
— Receipt of an EnviraCOM™ command instructing
the S9200U1000 to exit Test Mode
— The cycling of power
