2. Installatin Instructins Separate the frnt panel frm back panel by depressing the tngue lcated in the tp f the unit. Pull the back panel ut. Line the back panel up against the wall r flat surface. Install three screws as required. Make electrical cnnectins as shwn n enclsed electrical wiring diagram. (Next page) Verify that yu have 24 VAC between terminals C and R. Install the cver t the back panel; first the tw tabs n the bttm and then the tp tngue. Push until tight against the wall. Wait fr 15 secnds fr the LCD display t appear (cmpletin f pwer circuit charging and fr self-diagnstics). 3.

The length f the cable fr the external sensr is 100 feet (30 meters) with standard cable. If lnger distance is needed then the cable MUST be shielded. 3
6. Technician tings 6.1 differential fr 0 10Vdc. The temperature Differential defines the rati between the pening level f the damper and the temperature demand. The damper will be fully pened when the demand (demand = ambient temp set temp) equals the differential. (Differential range: 2 C 10 C) Press and hld the MODE buttn a number will appear n the display. Adjust the differential using the + r - buttns. (In the picture the differential was 2 C and cha nged t 6 C) 6.2 Prprtinal utput selectin 0 10Vdc r 2 10Vdc Press the MODE buttn again - 0 and SET will appear n display. Using the + buttn, change the scale t 2 10Vdc 2 will appear n display. Using the - buttn, change the scale t 0 10Vdc 0 will appear n display. Press the MODE buttn again t return t nrmal display mde. (In the picture the scale was 2 10Vdc and changed t 0 10Vdc) 6.3 set fr temperature reading. The set is used fr field calibratin f the measured temperature if necessary. (set range -6 C 6 C) Press the MODE buttn again a number will appear n the display. Change the set fr ambient temperature using the + r - buttns. Press the MODE buttn again r wait t return t nrmal display mde. (In the picture the ffset was 0 C and changed t -2 C) Nte: If n key is pressed fr 5 secnds, the thermstat will autmatically return t nrmal display mde. 4
