Menu 2-08 Control time base
The control quality depends on parameters like the building's insulation, the number of radiators or the ooring
type. The “Tips” column in the following table will help you select the seing that is appropriate for your setup.
Default seing: 15 minutes.

(1) The control is ed with anti-short cycle protection to suppress start or stop requests when they are too short.
The anti-short cycle duration is 10% of the time base selected (e.g.: if the time base is set to 30 minutes, the anti-short
cycle will be 3 minutes, i.e. the thermostat will not accept any start or stop requests that are under 3 minutes).

Menu 2-11 Hysteresis seing (if 2-08 = tor)
Default seing: 0.4°C.
Adjusts from 0.2°C to 2°C,
in increments of 0.1°C.
Menu 2-06 does not appear if your Tybox is
linked with the Tydom app (menu 1-10 = 1).
If you don't want to use this function, leave
the seing on “---”.
Example:
Setpoint 20°C. Hysteresis 0.4°C.
Heating request if T° measured <19.8°C.
Heating shuts down if T° measured> 20.2°C.
