CH Minimum Capacity sets the lowest limit of the CH capac-
ity. The appliance capacity can be dened by adjusting this
value and the CH Maximum capacity. It is therefore possible to
adjust the CH capacity to the installation needs.
Example: when the CH minimum capacity is set to 20%, the
real appliance capacity is the appliance minimum capacity
plus 20% of the dierence between the maximum and mini-
mum capacity.
Adjust the CH Minimum Capacity using the LEFT or RIGHT
keys, then store the setting with the OK key.
Default: 0%
Absolute Max CH Setpoint limits the setpoint during a cen-
tral heating call. This setting can be used to prevent a user from
adjusting the central heating setpoint or outdoor curve above
a safe operating temperature in the EZ Setup Menu. A warn-
ing screen will be displayed in EZ Setup if the user attempts to
raise the setpoint above the Absolute Max CH Setpoint. The
Absolute Max CH Setpoint will be displayed on the outdoor
curve in EZ Setup if the user selects an outdoor curve which
goes above the Absolute Max CH Setpoint.
Adjust the Absolute Max CH Setpoint using the LEFT or RIGHT
keys to then store the setting with the OK key.
Default: 186°F
CH1 Max. Setpoint is the maximum setpoint for a CH1
heating call when an Outdoor Curve option is chosen in
Demand Type. CH1 Maximum Setpoint is the xed setpoint
for a CH1 heating call when a Setpoint option is chosen in
Demand Type.
Adjust the CH1 Maximum Setpoint value using the LEFT or
RIGHT keys, then store the setting with the OK key.
Default: 180°F
CH1 Min. Setpoint is the minimum setpoint for a CH1
heating call when an Outdoor Curve option is chosen in
Demand Type. This setting is not applicable when a Set-
point option is chosen in Demand Type.
CH1 Min. Setpoint must be set equal or below the CH1
max. setpoint.
Adjust the CH1 Minimum Setpoint value using the LEFT or
RIGHT keys, then store the setting with the OK key.
Default: 80°F
