.............................It's the most basic system you can get.
Fk all to do with the proghrammer Billy. You Have a loit to learn :wink:If you pull the programmer off ill bet only one channel is wired in, to get hot water only you have to turn off all lockshields.
where is the 22mm going up to ? is there just a auto air vent ?
likely c plan with pump under the floor or back boiler with pump an mv next to it

F&E probs
Just thinking out loud
Would not the 1/2" feed be running through a coil? - for domestic hot water.
Would not the tank be mostly full of HHW?
Would not the tank temperatures be controlled through a boiler stat on the front of the boiler?
Would not the heating be controlled by a thermostat operating a pump from the outlet of the HHW from the cylinder.
There may or may not be a pump from the top of the Glow Worm, if there is, it is circulating the water around the boiler piping and tank and most probably not doing the heating.

What else could it be then?
In the last 25 + years hot water systems have done a complete swing - 180 degrees.
Originally the cylinder was full of heating hot water and a coil was placed inside the cylinder to heat domestic hot water.
It also gave the customer instant heating - as soon as the thermostat started the pump - instant hot water to the panels.
Now cylinders have a heating hot water coil in them to heat a cylinder of domestic hot water.
This gives the consumer the amount of water in the cylinder as a storage / useable amount.
That's how I see it.
