Feature Request - Bosch CS6800i AW - Silent Mode - Electrical Power Reduction

[stegeb1]

DESCRIPTION

I am having a Bosch CS 6800iAW heatpump and try to figure out how to control maximum electrical power settings of the pump. There is a silent mode availabe for this pump which is implemented in EMSESP. In addition the system allows setting the maximum electrical power when in silent mode (silent mode: on, auto, off). This appears not be implemented in EMSESP right now. The power reduction setting is given in % reduction with a value range of (30%, 40%, 50% and 60%).

In EMS Silent mode is controlled by address 0x0484.
Power reduction setting is controlled by an UINT at offset 64/0x40.

UINT on 0x0484 offset 64/0x40
3 for 30%
4 for 40%
5 for 50%
6 for 60%
max power reduction

I have tested the feature extensively. The accepted value range is {3,..,6). Values are only accepted when silent mode is either on, or the auto mode and the auto time setting condition is fullfilled. Values are not accepted in off mode.

Silent mode and silent mode power setting is an official bosch feature and can be set by e.g. the Bosch BC400 thermostate.

I am using this mode to reduce the power over night, and in autumn time to limit the total electrical energy consumption by the pump.

Can this be implemented in an upcoming EMSESP release ?

Thanks,
Berthold
