Heating / Cooling Zones - Siemens TUTORbit POL687 Instructions For Installation, Use And Maintenance Manual

4 - INSTALLATION

4.11 - Heating / Cooling zones

The heating zones can work independently to each other and
in various modes, which can be selected in Configuration-
>Zones ->Zone n. mode.
The heating modes are:
- FixSp-RT (heating/cooling at constant temperature): closing
the room thermostat input generates a heat/cool demand
and the start of the sensor temperature control cycle Water
Heater T.
With the Parameters->Zones->Action command you can
set the heating zone in Automatic (weekly programme) or
Manual (fixed setpoint) mode.
If the RT corresponding to that circuit is opened, the heating
will always stop.
- Outd Reset-RT (Heating/Cooling according to the outdoor
reser). The calculation algorithm (see Figure 4-7 or 4-8) of
the outdoor sensor generates the setpoint of the heating/
cooling zone.
With the Parameters->Zones->Action is possible set the
circuit in Automatic (weekly programme) or Manual (fixed
setpoint) mode.
The heating also stops when the outdoor temperature has
exceeded Parameters->Modules->Spring Temp.. Similarly,
cooling ends when the outside temperature drops below
Parameters->Modules->Autumn Temp.

TUTORBIT
Opening the room thermostat input, corresponding to that
circuit, always causes a stop of the service.
The parameters for adjusting the outdoor reset can be found
in Parameters->Modules->Heat. Outdoor Reset and are:
- Incline
The incidence of this parameter can be seen in figure 4-7.
- Slippage
The incidence of this parameter can be seen in figure 4-7.
- Minimum Temp.
Minimum temperature of the heating supply, for any Incline
or Slippage condition.
- Maximum Temp.
Maximum temperature of the heating supply, for any Incline
or Slippage condition.
