from the saving mode temperature.
A typical saving restart period is 120 minutes.
Whist in the saving mode, the ems controller must look ahead in the self-learning matrix for a ready period by the time
defined by the saving restart period (S r). For example, the ems controller looks 2 hours ahead.
If the ems controller detects an ready period, the ems controller starts to lower the product temperature, as shown below.
The ems controller switches to the saving mode if there are no ready periods within the next 2 hours as defined by the sav-
ing restart time (S r).
The ems controller ignores periods of inactivity if the time to the next active period is less than the saving restart time.
For example, the diagram below shows a period of inactivity, saving (0) at 18:00 followed by two monitor (1) periods. In this
instance, the ems controller would ignore the saving (0) at 18:00 and switch to the saving mode at 19:30.
Note:
ems controllers always run in the ready mode for periods in the self-learning matrix that are set to 1
l
(monitor) or 2 (ready).
In the following example matrix, the ems controller will start to cool by the saving restart period before the ready period (2),
run in the ready mode for 30 minutes, and then switch to the saving mode (assuming no delay to saving dsparameter is in
operation).
