The 

GEN II-R

is  equipped  with  a 

Digital  Display  (G)  that  constantly displays Leaving  

Air Temperature from the unit.

 The display and 3 buttons beneath the display provide the  

installing contractor the ability to tailor the system to your specific application.

The 

GEN II-R

controller is shipped from the factory configured for basic Gas/Electric operation. 

However, the following should be checked as part of the initial installation setup procedures:

1.   

EH

jumper 

(F)

is installed by the factory on one pin for normal gas heat operation where the fan 

is controlled by the HVAC system fan control.  When a fan output is required from the GEN II-R 

controller on a call for heat, place the 

EH

jumper over both pins for several seconds and then 

remove.  Place the jumper tab on one pin.

2.   

O/B

and

HP

jumpers 

(F)

should both be on one pin or removed, for GE operation.

3.   

PRIORITY

jumper 

(F)

should be on one pin.

4.   Set the power switch 

(E)

to 

ON

.

5.   Set the 

NIGHT DAY

switch 

(J)

to the 

DAY

position.

6.   Set the fan jumper 

(I)

to 

AUTO

for intermittent operation or 

ON

for constant ON operation in the 

Occupied mode. 

7. Place the 

LOCK

UNLOCK

switch 

(K)

in the UNLOCK position.

8. Place the 

TIME/TEMP

jumper 

(I)

on the middle and upper pins to control Y2 and W2 staging on 

run time and supply air temperature.

GEN II-R 

Gas Electric Advanced Feature Configuration

Gas Electric Capacity Control - Cool and Heat cut-out temperature adjust

The factory setting for the Cool and Heat cut-out temperatures is 45°- 145°F (7°- 62°C).  This can 

be easily changed with the following procedure:

1.

Cool  cut-out  temp

– Press  the  DN  button 

(H)

; “C”  will  be  displayed  and  then  the  cut-out 

temperature.

2. LOWER – Press the DN button; after the “C” is displayed, continue to hold the DN button until 

the desired temperature is displayed; then release.

NOTE: The controller will not change the Cool cut-out lower than 40°F (4°C).

3. RAISE – Press  the  DN  button;  after  “C”  is  displayed,  immediately  release  the  DN  button  and 

press the UP button.  Hold until the desired temperature reading is displayed and release.

4. Press the DN button to verify the new cool cut-out temperature.

Heat  cut-out  temperature

- Press  and  hold the  UP  button;  after  the  “H”  is  displayed,  use  the 

same procedure as above to raise or lower the displayed temperature.

Electric Heat - Fan Configuration

EH

jumper 

(F)

is installed by the factory on one pin for normal gas heat operation where the fan is 

controlled  by  the  HVAC  system  fan  control.    When  a  fan  output  is  required  from  the 

GEN II

controller  on  a  call  for  heat,  place  the 

EH

jumper  over  both  pins  for  several  seconds  and  then 

remove.  Place the jumper tab on one pin.

                    

GAS ELECTRIC BASIC CONTROLLER CONFIGURATION

2nd Stage Heat and Cool Cut-in / Cut-out Configuration

The GEN II-R controller is set up at the factory to stage Y2 and W2 cut-in operation based on a 3-min-

ute time delay and supply air temperature. This is done using the TIME/TEMP (I) jumper. Time may 

be field configured from 3-20 minutes by the contractor during system configuration. The cut-in 

temperatures are fixed in the controller program at 58°F (14°C) and higher for Y2 and 120°F (48°C) 

and lower for W2. The GEN II-R controller second stage cut-out temperature is fixed in the controller 

program at 50°F (10°C). Y2 will de-energize when it drops below 50°F and re-energize when it rises 

above 58°F. If the air temperature drops below the low cut-out (45°F) Y1 and Y2 are de-energized and 

the controller will go into a 5 minute purge mode. After 5 minute purge, if the temperature has risen 

above the low cut-out Y1 is re-energized. Heat W1 and W2 will de-energize if leaving air temperature 

rises above heat cutout and will be locked out for 5 minutes. After 5 minute lockout, if a heat call 

remains and leaving air temperature is lower than heat cutout, W1 will re-energize. By placing jumper 

on bottom two pins, a time only strategy may be configured into the system. ( see below);
