Underfloor Heating Do I have a fault

I have an underfloor heating system installed in the kitchen.
I have the programmer off & the temperature turned low, I have no flame symbol on the programmer & the pump is not running. So there is no call for heat.
When the programmer for the rest of the house calls for heat, my UFH is on, although the pump is not running.
What is wrong or is this to be expected?
I have the manifold as on the above link top right.

Manifold is incorrectly connected to your existing system it is common on this type of UFH to incorporate a 2 port zone valve on the flow to the manifold to stop the existing system circulation pump from influencing the flow though the UFH the Actuator should be wired so that once the valve has opened (on command from the UFH control,) the auxilary switch on the actuator starts the UFH pump I assume that there is a boiler interlock to start the boiler and shunt pump when there is a demands from the UFH when the main system controls are in an off period??

I have the install instructions & to me it looks like its installed as per instructions.
I have them as a pdf, just cant find where I got them from as I could have posted a link.
I will keep looking.

Just spoke to the manufacturer/supplier, they said there should be zone valves.
I cant see any, would zone valves be in the boiler? its a Greenstar highflow 440
