Installation programming

Note: Blank temperature settings may be entered at any of the four daily periods. When a setpoint is left blank and in an occupied condition, the ZSM will default to the last occupied setpoint. When a setpoint is left blank and in an unoccupied condi- tion, the ZSM will default to the last unoccupied setpoint.

Temporary Manual Override

While in normal run mode, depressing the hold temp button toggles the ZSM to the temporary manual override menu.

The mode will override any number of programmed setpoints through any of the 28 programmed periods. After entering setpoints and length of override time, these new settings are used in place of the setpoints programmed for normal run mode.

Time Button

•While in the program menu, each time you press and release the positive or negative side of the time button, the time will advance or decrease by ten minute increments. If you press and hold the positive or negative side (“minus” and “plus” keys), the ZSM will increment rapidly.

•When the display is in the normal run mode, each time you press and release the positive or negative side of the time button (“minus” and “plus”keys), the time will advance or decrease by one minute. If you press and hold the positive or negative side (“minus” and “plus” keys), the ZSM will increment rapidly.

Note: Blank temperature settings may be entered at any of the four daily periods. When a setpoint is left blank and in an occupied condition, the ZSM will default to the last occupied setpoint.

Keypad Lockout

If you simultaneously depress and hold both the positive and negative sides of the “minus” and “plus” keys for four seconds, the lock icon will appear and all keypad functions will lock out. If you repeat this operation, the lock icon will disappear and all keypad functions will be available again.

•Keypad lockout applies only to normal run mode and temporary manual override mode.

Day Button

•In normal run mode, depressing the day button will move the current day ahead.

•While in the program menu, depressing the day button will move you through the seven days of the week and allow you to program temperature settings for each of the four daily periods.

Erase Button

•Pressing the erase button while in normal run mode will turn off the check filter icon.

•Pressing the erase button while in the program menu, will erase all time and temperature setpoints of a given period.

•The erase button will acknowledge the failure buzzer (option 16) until 12:00 am.

Mode Button

•BAYSENS019 only: Pressing the mode

button toggles through all modes: off, heat, cool, auto, and emer (HP unit).

•BAYSENS020 only: Pressing the mode button while in normal run mode, or temporary manual override run mode, will toggle through both modes, off and auto.

Fan Button

•The fan button allows you to toggle between on and auto.

Up and Down Button Arrows

•Depressing ↑ or ↓ arrow while in normal run mode will cause your ZSM to toggle to the temporary manual override menu.

•Depressing either ↑ or ↓ arrow while in the program menu or temporary override menu will cause the temperature setpoint to advance or decrease in one degree increments.

•Depressing and holding either the ↑ or ↓ arrow will cause the temperature setting to increment rapidly.

Simultaneously depressing the ↑ or ↓ arrow for two seconds while in the program menu or temporary override menu will toggle the ZSM between an occupied and unoccupied condition.

Holdtemp Button

While in normal run mode, depressing the hold temp button toggles the ZSM to

a temporary manual override menu. See Figure I-P-4.

This mode overrides any number of programmed setpoints through any of the 28 programmed periods. After entering setpoints and length of override time, these settings are now used.
