2.2.5.2. Start-Up Delay in Room Sensor Mode
In Room Sensor Mode, the M3 unit controller initiates a start up delay on any power-up or reset (two minute default).
During the delay, no blower, heating, or cooling operation will occur. This delay may be adjusted using parameter 133 to
stagger the start of each unit, reducing the initial power demand. Adjustable range is 2 to 30 minutes.
Go to SETTINGS > RTU OPTION > EDIT PARAMETER =133 (ZON SENS STRTUP DLY)
2.2.5.3. Blower Operation (Occupied) in Room Sensor Mode
In Room Sensor Mode, default operation, the M3 unit controller cycles the blower with a heat/cool demand. The menu
path as listed in table 9 on page 11 will allow a change to continuous blower operation.
OCC (OCCUPIED) blower mode description:
AUTO CYCLE: Blower cycles with demand
ON-CONTINUOUS 1: Blower is on when either the occupancy sensor or occupancy scheduler indicate occupied.
ON-CONTINUOUS 2: Blower is on only WHEN BOTH the occupancy sensor and occupancy scheduler indicate
occupied.
ON-CONTINUOUS 3: Blower is only on when both the occupancy sensor and occupancy scheduler indicates
occupied. Blower will be on a minimum of 25% of the time when occupancy scheduler indicates occupied but the
occupancy sensor indicates not occupied. The 25% minimum is achieved by turning blower on for 30 minutes and
off for 90 minutes.
2.2.5.4. Room Sensor Parameters
Any of the parameters listed can be directly modified using the following method:
Go to SETTINGS > RTU OPTION > EDIT PARAMETER = (see parameters 63, 64, 74, 75, 101 - 104, 133 and 137
- 152)
