Horstmann SRT321 & Zipato

Zipato firmware up o date: 0.9.999.8k

Horstmann SRT321 + Boiler Actuator

SRT321 Wakeup intervall: 10 mn

Program in climate: 00h00-17h00: t°= 16.3

17h00-19h00: t°= 17.2

19h00-24h00: t°= 18.8

I add the following problems:

1- when program is running, it switch to "until next period" at SRT321's wakeup time.And setpoint_heating t° increase by itself to the next entire value.

For examp: 18.6°program => 19.0°when switching to next period. But t° in SRT321 chart shown 19.3°; then 19.5°.

Other sample: this morning the setpoint _heating t° was 16°. SRT321 increases by itself to 17° or 18° (see attached file SRT321_Problem2.jpg).

2- when I change setpoint_heating t° on SRT321, setpoint_heating t° changes in "climate".

when I change setpoint_heating t° in "climate", setpoint_heating t° doesn't change on SRT 321.

3- SRT321 send t° to the box at wakeup time (60 mn for ex.) even if the t° fo the room increases during that period. That means, if the t° of the room is low and need to be increased (2° more for example),

the boiler will warm the room during 60 mn and could go over the setpoint_heating t°.

All these problems make me not condident with SRT321.
