KEYPAD ACCESS

The dipswitches in the cover (shown above connected with
ribbon cable) must be set in order to lock the user out of
programming and/or to set the clock and schedule. Use the
guide below to set these dipswitches for your application.
Otherwise, user access may be limited with an access code
set in programming. (The fan and system switches are
enabled or disabled in programming only, and require no
dipswitch placement.) 

Keypad access to both programming
and clock setup. (This is the default
setting.)

No keypad access to programming or
clock setup.

Keypad access to programming only.

Keypad access to clock setup only.

Once the dipswitches have been set and you have confirmed
that the sensors are reading correctly (and program and
clock setup are finished, if locking out access with dip-
switches), secure the cover to the base with the two set
screws located at the top right and the left side to prevent
tampering.

Setup                                

Note: 

If using remote sensor(s), the calibration may need to

be adjusted. See “Checkout and Troubleshooting” section.
