RANGE COMMENTS
-28 to 21 This item lets you modify Cooling setpoint 1
-28 to 21 This item lets you modifyCooling setpoint 2
-28 to 0 This item lets you modify the ice storage setpoint.
-26.6 to 60 This item lets you modify Heating setpoint 1, only displayed for heat pumps.
-26.6 to 60 This item lets you modify Heating setpoint 2, only displayed for heat pumps.
3.8 to 50 Automatic changeover threshold, cooling mode. This item lets you display and modify the outdoor
temperature threshold at which the unit changes over in cooling mode. Displayed only if the auto cooling/
heating changeover function is selected.
0 to 46 Automatic changeover threshold, heating mode. This item lets you display and modify the outdoor
temperature threshold at which the unit changes over in heating mode. Displayed only if the auto cooling/
heating changeover function is selected and if the unit is a heat pump. The heating threshold must be
3.8°C below the cooling threshold, otherwise the new setpoint will be rejected.
35 to 60 This item lets you display and modify the heat reclaim setpoint.
2.7 to 15 This item lets you display and modify the heat reclaim dead band.
0 to 100 Demand limit 1 setpoint. Limitation by volt-free contact. This item is used to define the maximum
capacity that the unit is authorised to use, if the demand limit contact(s) activate limit 1. Contact control
depends on the configuration.
0 to 100 Demand limit 2 setpoint. Limitation by volt-free contact. This item is used to define the maximum
capacity that the unit is authorised to use, if the demand limit contact(s) activate limit 2. Contact control
depends on the configuration. Displayed and used only for units with energy management option.
0 to 100 Demand limit 3 setpoint. Limitation by volt-free contact. This item is used to define the maximum
capacity that the unit is authorised to use, if the demand limit contact(s) activate limit 3. Contact control
depends on the configuration. Displayed and used only for units with energy management option.
0.1 to 1.1 Cooling ramp loading rate. This parameter is only accessible if the ramp function is validated in the User
Configuration 1 menu. This item refers to the maximum permitted water heat exchanger low temperature
rates (°C/min). When capacity loading is effectively limited by the ramp, mode 7 is active.
0.1 to 1.1 Heating ramp loading rate. This parameter is only accessible if the ramp function is validated in the User
Configuration 1 menu. This item refers to the maximum permitted water heat exchanger high temperature
rates (°C/min). When capacity loading is effectively limited by the ramp, mode 7 is active.
