Temperature boiler 1 (through 8)
HS State
Status (On/Off) boiler 1 through 8
T-Solid Fuel
At boiler 2 = Boiler for solid fuel (A7)
T-Return 1
Return flow temperature of HS 1
T-Return 2
Return flow temperature of HS 2
T-Return total
Installation return flow temperature

current warm water set temperature as
per heating program and operating
mode

section (infeed/solar)

Installation
T-Outside [F9]
The measured outside temperature is smoothed for
control purposes. The smoothed value is displayed here.
Ext setpoint [F15]
The 0-10V input can be used to preset an accumulative
set value for the control system (see V-CURVE p. 26).
T-Header (only for Cascades) [F8]
The set value appears after the F button is pressed. The
set value corresponds to the maximum required
temperature of the consumer circuits from the heating
system (incl. hot water preparation). The mixer circuits
request the tempe heating curve distance (expert
value).
T-HS [F8 or BUS]
Current measured temperature of all connected heat
generators (only if sensors are present)
HS State
Additionally it is indicated whether the heat generator is
switched on; in the case of two-stage heat generators,
the status of the second stage is also displayed.
T-Return total [F17]
Return flow temperature for start of the refrigeration
machines (see [T-Return cooling]).
T-Buffer T/M/B [F3/F2/F1]
(only if buffer storage is installed)
Buffer storage tank temperatures in the discharge area,
the charging area and the infeed of alternative energy.
Mod depth
Display the required degree of modulation calculated and
the current modulation levels for all active heaters. The
ad is only when the corresponding figures are available
(configuration, BUS, etc.).
Hot-Water
T-DHW Rated (hot water set temperature)
Display of the currently valid value for control.
T-DHW (hot water temperature) [F6]
Display of measured upper storage tank temperature.
DHW-T B (storage tank bottom temp.) [F12]
For example for solar or solid fuel infeed or for active
charge-through function (CHARGE-THROUGH = 01).
Display hot-water tank temperature in infeed area.
T-Circulation (return flow temperature of circulation)
Only if temperature control of the circulation function is
activated.
