1. If the BMS sets the schedule from their master schedule, the schedule set in the
iTM
should be
disabled. See section 7.2 (1.) in Part 2.
2. How to Program
• BMS to set Setpoint Range Limitation to mater/-2°F from the occupied setpoints.
• BMS to set Occupied Setpoints and Unoccupied Setpoints.
• BMS to set Timed Override Time (override is handled by
iTM
with the Timed Override Minutes).
• BMS to set the occupancy status based on the Master Schedule. The BMS may send the
occupied setpoints if the BMS wants to reset the occupied setpoints when the occupancy
status is changed.
2.1 Setpoints
1. Refer to sections 7.2 (6.) – 7.2 (9.), 7.2 (14.), and 7.2 (15.) in Part 2.
2. The Occupied Setpoint can be set via the
iTM
or BMS schedule, or manually from the
iTM
or
BMS remote controller. The setpoint stored in the indoor unit is based on the last command
(last setpoint) received as the indoor unit does not recognize priority arrays.
3. The Unoccupied Setpoints can be set via the schedule (
iTM
or BMS) or manually from the
iTM
or BMS. Enable the setback at the
iTM
during its commissioning. The BMS can monitor and
adjust the unoccupied setpoint if set at the
iTM
.
