Hopefully one of you kind experts can help me please
I have the above MA1 actuator on my system and it works well apart from it will not stay on the MID point when HW and CH are requested at the same time (it just defaults to hot water only in this instance). If just CH or just HW are requested it moves across perfectly and works as expected.
Any thoughts on what I can do - it has never worked properly right from the outset and is only 12 months or so old
many thanks in advance
