QUICK START AND COMMISSIONING
Follow these Quick steps for a successful job
If you need additional information, please read the GEN II-R Manual
1. Install GEN II-R controller in an easily accessible location for your customer.
2. Install an independent 24 volt 40 VA transformer if using 3 wire (run open-run closed damper), and connect to the TR1
and TR2 (next to TC/TC) terminals on the GEN II-R controller. When using a TR series 2 position / spring return damper
the transformer VA needs to be sized based on damper quantity. See page 19 for transformer sizing.
3. Install the LAT sensor in the supply air, ahead of any bypass takeoffs. Wire sensor to the S S terminals on the
GEN II-R controller.
4. Install Dampers and Bypass Damper.
5. Install all field supplied programmable thermostats sub-bases and pull 18/4 thermostat wire to the damper
control board that it will control. For Heat Pump operation with emergency heat, install one Heat Pump thermostat
with emergency heat operation on any zone using 18/5 thermostat wire to that one thermostat.
6. Wire TR1 and TR2 terminals from the GEN II-R controller to the first damper control board R and C - only (18 ga
thermostat wire).
7. Wire A & B terminals from GEN II-R controller using Belden 8740 twisted pair wire or Zonex supplied equal to
the first damper control board A & B - only.
8. Damper wiring is factory per wired to the damper control board.
9. Wire the first thermostat to it’s damper control board R, C, Y, W/OB and E if using emergancy heat in Heat Pump
operation.
10. Address the the first damper control board jumper as #1- see pages 10 and 11 for thermostat installation and
addressing. Note: Each damper will have a unique address 1-10.
11. Turn on GEN II-R controller switch “E”. Power light should light up and look at the display “G” on the GEN II-R
controller, and the #01 should appear on the display. This indicates you are communicating with the first zone
damper / thermostat.
12. If you don’t see the #01 and 00 is displayed, check the address jumper on damper control board. If the
address is #01, then check wires for TR1 & TR2 or R & C polarity and A & B for correct connections.
13. If #01 is displayed on the GEN II-R controller, then daisy chain wires from damper control board #1 to the next
damper control board and address it #2; then repeat the ON-OFF switch operation and confirm the #02 shows
up on the display indicating the system is now communicating with 2 thermostats.
14. Continue adding damper control boards; and confirm communication by repeating the ON-OFF switch opera-
tion until all thermostats are wired and the total number of thermostats on the job show up on the display on
the GEN II-R controller.
15. Go to any thermostat and make a Cool Call. Look at the GEN II-R controller and confirm Y1 (yellow LED) and
G (green LED) lights are ON.
16. Satisfy the Cool Call at the thermostat to be sure Y1 and G turn OFF at the GEN II-R controller.
17. Repeat with a Heat Call for W1 (red LED).
18. Wire GEN II-R controller to the A/C unit.
19. Set thermostat to call for cooling, and check register to be sure each damper opens and closes as you make
and satisfy the call
.
