HW Cool OAT Ena<br />
Displays and edits the outside air temperature that<br />
when above the heat wheel will be enabled, when in<br />
outside air temperature operation.<br />
Range: 50-100 °F<br />
Default: 80 °F<br />
HW Effic Offset<br />
Displays and edits the number of degrees the outside<br />
air temperature has to be below the supply<br />
temperature setpoint in heating before the heat wheel<br />
is enabled in space temp mode. This setpoint is<br />
designed to counteract the efficiency of the heat<br />
wheel vs. the heat rise of the units heat source on low<br />
fire/minimum heat output.<br />
Range: 0-50 °F<br />
Default: 5 °F<br />
HW Humid LockOn Sp<br />
Displays and edits the outside air humidity that will<br />
force the heat wheel to run any time the exhaust fan<br />
is enabled.<br />
Editable<br />
Range: 0-100%<br />
Default: 65%<br />
HW OAT High LockOn<br />
Displays and edits the outside air temperature at<br />
which when above the heat wheel will be forced on<br />
when the exhaust fan is enabled.<br />
Range: 90-150 °F<br />
Default: 85 °F<br />
HW OAT Low LockOn<br />
Displays and edits the outside air temperature at<br />
which when below the heat wheel will be forced on<br />
when the exhaust fan is enabled.<br />
Range: -50-100 °F<br />
Default: 45 °F<br />
HW Start Sel<br />
Allows user to select if the heat wheel is controlled<br />
based on space temperature verses outside air<br />
temperature and supply setpoint, or based only on<br />
outside air temperature verses supply setpoint. OAT<br />
only will be automatically selected if a space sensor<br />
is not installed<br />
32. OAT Only<br />
33. Space Temp (default)<br />
Editable<br />
HW Exh Low Limit<br />
Displays and edits the exhaust air temperature that<br />
will put the unit into frost protect mode. If the unit is<br />
equipped with a VFD the heat wheel will slow down<br />
until the setpoint is maintained. If the unit is not<br />
equipped with a VFD the heat wheel will be jogged<br />
off and on to maintain setpoint.<br />
Range: 0-45 °F<br />
Default: 20 °F<br />
