Revert "fix(poolsana_heatpump): device does not like multi-dps commands"

This reverts commit 1ba05491156ad6ffeafcb900defba1e2f2698236.

Issue was misdiagnosed as being related to multi-dps writes.
In fact it is the device that is toggling dp 1 on any write,
regardless of what is being written, contrary to normal convention.

Issue #6201
