Depending onthe system water volume and the heat emitters type, the heat up orcool down of a space can take longer. This setting can compensatefor a slow or a quick heating/cooling system during the heat up/cooldown cycle.Note: The setting of the emitter type will influence the maximummodulation of the desired leaving water temperature and thepossibility for usage of the automatic cooling/heating changeoverbased on the indoor ambient temperature.Therefore it is important to set this correctly.# Code Description[A.3.1.1.7] [9-0B] Emitter type:Reaction time of the system:▪ Quick Example: Small water volumeand fan coils.▪ Slow Example: Large water volume,floor heating loops.8.2.6 Contact/helpdesk number# Code Description[6.3.2] N/A Number that users can call in case ofproblems.8.3 Advanced configuration/optimization8.3.1 Space heating/cooling operation:advancedPreset leaving water temperatureYou can define preset leaving water temperatures:▪ economic (denotes the desired leaving water temperature whichresults in the lowest energy consumption)▪ comfort (denotes the desired leaving water temperature whichresults in the highest energy consumption).Preset values make it easy to use the same value in the schedule orto adjust the desired leaving water temperature according to theroom temperature (see modulation). If you later want to change thevalue, you ONLY have to do it in one place. Depending on whetherthe desired leaving water temperature is weather dependent or NOT,the desired shift values or the absolute desired leaving watertemperature should be specified.NOTICESelect preset leaving water temperatures in accordancewith the design and selected heat emitters to ensure thebalance between desired room and leaving watertemperatures.# Code DescriptionPreset leaving water temperature for the main leaving watertemperature zone in case of NOT weather dependent[7.4.2.1] [8-09] Comfort (heating)[9‑01]°C~[9‑00]°C (default: 45°C)[7.4.2.2] [8-0A] Eco (heating)[9‑01]°C~[9‑00]°C (default: 40°C)[7.4.2.3] [8-07] Comfort (cooling)[9‑03]°C~[9‑02]°C (default: 18°C)# Code Description[7.4.2.4] [8-08] Eco (cooling)[9‑03]°C~[9‑02]°C (default: 20°C)Preset leaving water temperature (shift value) for the main leavingwater temperature zone in case of weather dependent[7.4.2.5] N/A Comfort (heating)–10°C~+10°C (default: 0°C)[7.4.2.6] N/A Eco (heating)–10°C~+10°C (default: –2°C)[7.4.2.7] N/A Comfort (cooling)–10°C~+10°C (default: 0°C)[7.4.2.8] N/A Eco (cooling)–10°C~+10°C (default: 2°C)Temperature ranges (leaving water temperatures)The purpose of this setting is to prevent selecting a wrong (i.e. toohot or too cold) leaving water temperature. Therefore the availabledesired heating temperature range and desired cooling temperaturerange can be configured.NOTICEIn case of a floor heating application it is important to limitthe:▪ maximum leaving water temperature at heatingoperation according to the specifications of the floorheating installation.▪ the minimum leaving water temperature at coolingoperation to 18~20°C to prevent condensation on thefloor.NOTICE▪ When adjusting the leaving water temperature ranges,all desired leaving water temperatures are alsoadjusted to guarantee they are between the limits.▪ Always balance between the desired leaving watertemperature with the desired room temperature and/orthe capacity (according to the design and selection ofthe heat emitters). The desired leaving watertemperature is the result of several settings (presetvalues, shift values, weather dependent curves,modulation). As a result, too high or too low leavingwater temperatures could occur which lead toovertemperatures or capacity shortage. By limiting theleaving water temperature range to adequate values(depending on the heat emitter), such situations can beavoided.Example: Set the minimum leaving water temperature to 28°C toavoid NOT to be able to heat up the room: leaving watertemperatures MUST be sufficiently higher than the roomtemperatures (in heating).# Code DescriptionLeaving water temperature range for the main leaving watertemperature zone[A.3.1.1.2.2] [9-00] Maximum temp (heating)37°C~55°C (default: 55°C)
