Set optimisation
(only with RAMSES 831 top2/RAMSES 832 top2)
The optimisation function allows you to achieve a certain room temperature at a desired switching point. The display shows how many minutes earlier the heating has to be started. This time applies per K of temperature difference between actual temperature and the desired setpoint temperature.
Example:
In the bathroom at 06.00 a change is programmed from reduction (17 °C) to comfort temperature(23 °C).
Without the optimisation function, the room thermostat stops heating request for bathroom at 06.00. Depending on the size of the room and heating system used, the bathroom reaches the desired 23 °C at 06.30, for example.
With a set optimisation of 5 min/K, the thermostat requests the heating requirement earlier as follows:
• Target temperature at 06.00 --> 23 °C
• Actual temperature --> 17 °C
• i. e. Delta T = 6 K
- 6 ~K^* 5 ~min / K = 30 ~min
The controller starts the heating 30 mins earlier and reaches the target temperature at 06.00. The optimisation value depends on spatial and heating setup.
▶ Confirm OPTIMISE by pressing OK.
➢ Use the + or – keys or rotary control to set the value (of 1–60) and confirm by pressing OK.
Set pump protection
Pump protection is not activated in the factory. But it can be set in the PROFESSIONAL SETTINGS menu.
➢ Confirm PUMP PROTECTION by pressing OK.
Use the + or - keys or the rotary control to select ON or OFF and confirm by pressing OK.
➢ Set TIME and DURATION using the + or - keys or the rotary control and confirm by pressing OK.

Set external input
The external input on the RAMSES 831 top2/ RAMSES 832 top2 can be configured for various external sensors.
CAUTION! Input is active, therefore do not use external voltage. The connected contact must be floating and electrically isolated.
▶ Confirm EXT INPUT by pressing OK.
➢ You can choose from UNUSED INPUT, FLOOR SENSOR, ROOM SENSOR, WINDOW SWITCH, PHONE SWITCH, PRESENCE DETECTOR.
➢ Confirm desired sensor/contact by pressing OK. Select available options and confirm by pressing OK.
The following options are available with the individual sensors/contacts

| Phone switch: Temperature selection Select temperature level for controller when the phone switch is switched on. |
| Time selection Select time until phone switch turns off automatically. |
| PHONE SWITCH is shown on screen if the phone switch is switched on. The switched contact must be switched off manually to allow the control to be used again. A safety shutdown switches the contact off again automatically at the preset time. The telephone remote switch used should have a pulse output. |
Set controller
Controller characteristics of pulse duration controller
With adapted heating systems, a PD controller is noted for its short transient time, minimal overshoot and therefore high control, accuracy.
Controller characteristics of a hysteresis-/on/off controller
With over or undersized heating systems, hysteresis controllers are noted for their minimal switching frequency and low temperature variations.
➢ Use + or – keys or rotary control to implement settings and confirm by pressing OK.
▶ Confirm CONTROL by pressing OK.
You can choose between PD CONTROL or HYST CONTROL.

Set optimisation
(only with RAMSES 831 top2/RAMSES 832 top2)
The optimisation function allows you to achieve a certain room temperature at a desired switching point. The display shows how many minutes earlier the heating has to be started. This time applies per K of temperature difference between actual temperature and the desired setpoint temperature.
Example:
In the bathroom at 06.00 a change is programmed from reduction (17 °C) to comfort temperature(23 °C).
Without the optimisation function, the room thermostat stops heating request for bathroom at 06.00. Depending on the size of the room and heating system used, the bathroom reaches the desired 23 °C at 06.30, for example.
With a set optimisation of 5 min/K, the thermostat requests the heating requirement earlier as follows:
- Setpoint temperature at 06.00 --> 23 °C
• Actual temperature --> 17 °C
• i. e. Delta T = 6 K - 6 ~K^* 5 ~min / K = 30 ~min
The controller starts the heating 30 mins earlier and reaches the setpoint temperature at 06.00. The optimisation value depends on spatial and heating setup.
▶ Confirm OPTIMISE by pressing OK.
➢ Use the + or - keys or rotary control to set the value (of 1–60) and confirm by pressing OK.

Presence detector: Temperature selection this temperature is controlled when the HVAC output on the presence detector is switched on. If no presence is detected, the set program is used.
Window switch: no options, provided the window switch is switched on, the thermostat controls to frost protection temperature level; WINDOW SWITCH is shown in display.

Controller characteristics of pulse duration controller
With adapted heating systems, a PD controller is noted for its short transient time, minimal overshoot and therefore high control, accuracy.
Controller characteristics of a hysteresis-/on/off controller
