1. the total on time for the valve to enable software to
2. average on time for the valve
3. maximum temperature ever encountered together
4. date of last service and service man's ID - 4 bytes
5. identification code for the controller
The formula in Fig. 4 is used by software to continually
update the digital trimming register and so compensate
the V3023 for the ambient temperature.
The timer is used to measure the duration the valve is
on.
The alarm feature is used to turn the controller power
on and off at the time programmed by software. The
V3023 pulls IRQ active low on an alarm even in
standby and thus can control the power on/off switch for
the controller.
The user RAM provides the controller with non-volatile
RAM for vital parameters, for example:
compute energy usage and also to identify when
service is needed
