Rated 5 out of 5 by mid position valve value for money valve and compact to be installed in some very small spaces.... 09-Jul-2014
Rated 1 out of 5 by Ditto Fenderer. This is really a review of Horsmann's poor quality and backward incompatible products strategy. Firstly - I've had an F223 for less than 15 months and the head circuit board has blown. Searched high & low for the receipt, can't find it so need to re-buy a head. Secondly - Can't buy just the head!!!!! have to buy the whole head & valve. Thirdly - can't even buy the whole thing and just bin the valve. As Fenderer (thank you mate) points out, the replacement product (Z223) head doesn't fit the F233 brass. So instead of a quick clip-on and wire-in I have to drain the system. Lastly, the only good bit. Because Fenderer clued me in, I don't have to re-buy Horsmann. 29-Mar-2014
Rated 1 out of 5 by WILL NOT FIT F322 VALVE BODY I bought this Z322 diverter as it was advertised as a direct replacement for the F322 enabling the control box to be swapped without changing the valve body. This is NOT possible. The valve body design is completely different and there is no detach button like on the previous model. You cannot fit the Z322 control box to a valve body F322. So now I have to drain the system down can fit the valve body with all the hassle that involves. Not at all impressed. 17-Nov-2013
Rated 4 out of 5 by Not The Same As Previous Model Valve went wrong so not being a plumber bought what looked like exactly the same valve for ease of installation Fitted it no probs with the actuator arm in the same place as the old one.........heating worked in reverse.....turned on central heating,got hot water etc etc The Problem?. I had fitted it upside down as valve looked the same but model changed. For the plumbers out there A and B flow reversed from old model.It is marked up correctly but being an amature didnt look.....my fault entirely 22-Jul-2013
