Heating
With outside mild temperatures the thermal requirements are reduced.
The internal comfort can also be obtained with a lower setpoint.
Example:
dS02 = 20°C
dS04 = - 7°C
dS06 = -5°C
setpoint = 35°C
compensated setpoint = 28°C
Heat Description
dS02
Temperature controller dynamic differential proportional band in Heat
dS04 Maximum temperature controller dynamic differential in Heat
dS06 Set point dynamic differential of external air
7.11 Water set point compensation with ambient temperature
Only with ambient keyboard option.
Function and parameters are the same of paragraph “Water set point compensation with external temperature”
On the ambient keyboard set parameter Cr 30 = 10
It is possible enable ambient compensation OR external compensation, not ambient AND external compensation.
7.12 Start-up report
Identifying the operating objective conditions is useful to control the unit over time.
With unit at steady state, i.e. in stable and close-to-work conditions, identify the following data:
•
total voltages and absorptions with unit at full load
•
absorptions of the different electric loads (compressors, fans, pumps etc)
•
temperatures and flows of the different fluids (water, air) both in input and in output from the unit
•
temperature and pressures on the characteristic points of the refrigerating circuit (compressor discharge, liquid, intake)
The measurements must be kept and made available during maintenance interventions.
7.13 97/23 CE PED directive
97/23 CE PED DIRECTIVE gives instructions for installers, users and maintenance technicians as well.
Refer to local actuation norms; briefly and as an example, see the following:
Compulsory verification of the first installation:
•
only for units assembled on the installer’s building site (for ex. Condensing c direct expansion unit)
Certification of setting in service:
•
for all the units
Periodical verifications:
•
to be executed with the frequency indicated by the Manufacturer (see the “maintenance inspections” paragraph)
