6.  Once the adjustable over-temperature switch setting is approximately at, or just below, the 

actual outlet water temperature, the unit should shut down. The 

FAULT

 indicator should 

start flashing and a 

HIGH WATER TEMP SWITCH OPEN 

fault

 

message should be 

displayed.  It should not be possible to restart the unit. 

7.  Reset the adjustable over-temperature switch to its original setting. The unit should start 

once the adjustable temperature limit switch setting is above the actual outlet water 
temperature.

5.6  INTERLOCK TESTS 

The unit is equipped with two interlock circuits called the Remote Interlock and Delayed 
Interlock. Terminal connections for these circuits are located in the I/O Box (Figure 2-12) and 
are labeled REMOTE INTL’K IN and DELAYED INTL’K IN.  These circuits can shut down the 
unit in the event that an interlock is opened.  These interlocks are shipped from the factory 
jumpered (closed).  However, each of these interlocks may be utilized in the field as a remote 
stop and start, an emergency cut-off, or to prove that a device such as a pump, gas booster, or 
louver is operational. 

5.6.1  Remote Interlock 

 

Remote Interlock 

1.  Remove the cover from the I/O Box and locate the REMOTE INTL’K IN terminals (see 

Figure 2-12). 

2.  Start the unit in the Manual Mode and set the valve position between 25% and 30%. 

3.  If there is a jumper across the REMOTE INTL’K IN terminals, remove one side of the 

jumper.  If the interlock is being controlled by an external device, either open the interlock 
via the external device or disconnect one of the wires leading to the external device. 

4.  The unit should shut down and display 

INTERLOCK OPEN

. 

5.  Once the interlock connection is reconnected, the 

INTERLOCK OPEN

 message should 

automatically clear and the unit should restart.
