TEC2604-4 and TEC2604-4+PIR BACnet® MS/TP Networked Multi-Stage Economizer Thermostat
Controllers Installation Instructions

PIR Diagnostic LEDs
The diagnostic LEDs inside the PIR lens brighten when
movement is detected within the first 30 minutes after
powerup. The LEDs do not light up or brighten after the
initial 30-minute period.
Setpoints
The installer must be certain that the difference
between the Occupied and Unoccupied setpoints can
be recovered within a timely fashion to ensure
occupancy comfort. In addition, the difference between
the two setpoints must be large enough to warrant
maximum energy savings.
These setpoints and Unoccupied time are adjustable to
allow for customization, as dictated by the individual
space requirements. See Figure 7 for an example of
increasing room temperature setpoints.
Configuring the TEC2604-4 or TEC2604-4+PIR
Thermostat Controller
The TEC2604-4 and TEC2604-4+PIR Thermostat
Controllers ship from the factory with default settings
for all configurable parameters. The default settings are
shown in Table 1. To reconfigure the parameters via the
thermostat controller, follow the steps in this section.

display indicating that the configured password is
required to proceed. Use the

Configuring Inputs DI1 and DI2
When DI1 and DI2 are configured for an alarm
condition, an alarm condition is displayed locally when
the input is closed. An alarm message is included on
the scrolling Status Display Menu and when the
message is displayed, the backlight momentarily
lights up.
