TDMA CONTROL 602-702 Eng Nov.doc

Party Switch:
On / Off
If the Party switch is set to “On” during the night or day setback periods, the
temperature setback is delayed until the party switch is set to “Off” again. If
the Party switch is not deactivated, the night setback waits until the following
night before coming active again.
The Party switch can also be activated by the TR-CONTROL. (see section
5.16.4)
See Technical Documentation on the TR-CONTROL for more information.
Operating Mode:
Auto htg + DHW / DHW only
Only DHW (Summer): The boiler and heating circuit pumps are switched off.
DHW heating is in operation. The heating circuit is active only for frost
protection.
Auto htg + DHW (Winter): Heating circuit pump, boiler and DHW heating in
operation. The heating circuit is active for frost protection.

Be aware of Legionella Regulations
5.7.1.1 Settings for a connected TR_CONTROL II Touch
Room Sensor
Active: Yes / No
If the CONTROL 602/702 and a TR-CONTROL II Touch are installed, then the
integrated room temperature sensor in the TR-CONTROL can be activated.
Only one circuit can be present in the reference room.
TR CONTROL:
Htg. allocation
If the CONTROL 702 is to control multiple heating circuits, each having a TR-
CONTROL II Touch, then each circuit can be allocated against a TR-CONTROL.
Assign a TR-CONTROL II Touch to each heating circuit: On start up of the TR-
CONTROL II Touch, press the screen where is says “Set ID”. You will get the
screen shown opposite. For Heating Circuit 1 press number 1, for Heating
Circuit 2 press 2, etc. The TR-CONTROL II Touch, after a few seconds revert to
the set time screen. Once this has bee set press the up key to go to main menu.
Note
The following 7 settings can be entered for each heating circuit (Set HC), as
long as each circuit has an active room sensor!
Heating off at 0…20 k against set
room temperature
Here the temperature difference between the actual room tenperature and the
target room temperature can be set. The boiler will then switch off and the
mixing valve closes. When a CONTROL 702 has several TR-CONTROL II
Touch’s connected, the controller will only shut off the boiler and the heating
pump when all the TR-CONTROL’s temperature differentials are met. The
hysteresis is factory set at 0.5 K
If a complete shutdown of the heating is not desired (eg. Set heating off at
20K) the system can still use the temperatures in the heating circuits during both
the day and night setback periods on the calculated flow temperatures to be
lowered.
