A. Check that the SZEM Environmental module and its components are properly installed.
B. Check all zone thermostats and dampers for proper installation.
C. Ensure polarity has been respected for all zone thermostat wiring and for the SZEM module.
D. Ensure all wires are properly inserted and screwed down in terminal blocks.
E. Tag all wiring and system components to correspond to the zone they serve.
F. If HVAC unit incorporates an economizer, it is important that it be checked for proper
operation and that the minimum positioning stop be set.
G. If the HVAC unit has an economizer that is not equipped with a relief damper, it may be
necessary to relink the return air damper so that it will always remain thirty percent (30%)
open, otherwise the bypass damper system may not perform properly.

C. Observe the condition of the following LEDs:
• W, Y, & G lights at zone inputs. LEDs to any zone input with a thermostat connected
must not be all ON; if they are, panel and thermostat are not communicating. Check
wiring for proper polarity. If a thermostat is not connected, these LEDs will be all ON.
NOTE: When proper communication is established, the satellite dish symbol ( ) should
appear on the thermostat LCDs and the uplink symbol ( ) should flash occasionally.
• On the SZEX Expander modules, the NORMAL WHEN FLASHING is flashing and the
MODULE CONNECTED is ON.
• Equipment outputs are not conflicting (i.e., W and Y LEDs not ON at same time).
NOTE: On initial power up, the control module will not respond to equipment calls for a
period of 4 minutes. Constant fan requests are serviced.
