SETPOINTS MENU [2]
ITEM | FORMAT UNITS | RANGE | COMMENTS | |
0 | ±nn.n | °C | See table below | This item lets you display and modify Cooling setpoint 1* |
1 | ±nn.n | °C | See table below | This item lets you display and modify Cooling setpoint 2* |
2 | nnn | °C | See table below | This item lets you display and modify Heating setpoint 1*, only displayed for heat pumps. |
3 [1] | nnn | °C | See table below | This item lets you display and modify Heating setpoint 2*, only displayed for heat pumps. |

5 [1] | ±nn.n | °C | 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. See section 5.2. Displayed only if |
|
|
|
| the auto cooling/heating changeover function is selected. |
|
|
|
|
|
6 [1] | ±nn.n | °C | 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. |

|
7 | nnn | % | 0 to 100 | Demand limit 1 setpoint. Limitation by |
|
|
|
| capacity that the unit is authorised to use, if the demand limit contact(s) activate limit 1. Contact control |
|
|
|
| depends on the unit type and configuration. See sections 3.6.4 and 3.6.5. |
8 [1] | nnn | % | 0 to 100 | Demand limit 2 setpoint. Limitation by |
|
|
|
| capacity that the unit is authorised to use, if the demand limit contact(s) activate limit 2. Contact control |
|
|
|
| depends on the unit type and configuration. Displayed and used only for |
|
|
|
| 3.6.5 for the contact control description. |
9 [1] | nnn | % | 0 to 100 | Demand limit 3 setpoint. Limitation by |
|
|
|
| capacity that the unit is authorised to use, if the demand limit contact(s) activate limit 3. Displayed and |
|
|
|
| used only for |

|
|
10 | ±nn.n | °C/min | 0.1 to 1.1 | Cooling or 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 rates of temperature drop in °C in the |
|
|
|
| evaporator. When capacity loading is effectively limited by the ramp, mode 7 is active. |
11 [1] | ±nn.n | °C | See table below | Zero reset threshold, cooling mode** |
12 [1] | ±nn.n | °C | See table below | Full reset threshold, cooling mode** |
13 [1] | ±nn.n | °C | See table below | Full reset value, cooling mode** |

2All points contained in this table can be modified.
*Those setpoints can be used for entering or leaving water temperature control. By default the unit controls the evaporator entering fluid temperature. Leaving fluid temperature control requires a parameter modification in the Service Configuration menu.
**These parameters are only accessible when reset based on OAT or delta T has been selected in the User Configuration 1 menu. See section 4.3.11.3 & 5.6.2.
