Wiring the Setback/Boost (P+, P-)
YELLOW
• The Setback feature can be used to provide the HWE-MOV with a lower temperature Set Point when less heat
is required.
• A typical use for Setback is to provide less system temperature to a building during the night or on the
weekends when building is not occupied, but heat is still required.
• The Setback is activated by closing/shorting the P+ and P- terminals using an external timer.
Button and Navigating Menus
The HWE-MOV has three buttons.
• The SET button function varies. When the Default Screen is displayed, pressing the SET Button views the

• When in the menus, pressing the Up and Down buttons will scroll through the menu options. They can be used
to change the setting of a specific function. i.e., change the Set Point, Differential, or System Trim. In addition,
when in the default screen, the Up and Down buttons will display the outdoor temperature and Outdoor Cutoff
T1 COM T2 COM T3+ T3- EXT+ EXT- P+ P- COM 24VAC
when no return sensor is available, or the outdoor temperature and the return temperature when an active return
sensor is connected.
• At the end of every operation menu there is a <Back> option that allows the user to go back one menu level. If
the SET Button was held down for three seconds on the <Back> option, the display will go back to the default
screen.

Startup Options

When the control is initiated for the first time or after a manual reset, it will start
its operation with the Startup Menu. Later, the Startup menu can be accessed as
an option from the operation menu. An option must be accepted in each screen in the Startup Menu to move to the next level.
