How to mount an actuator and wire a Smatrix Controller

In our latest underfloor heating installation video, Martin Allen goes through the following:
1) How to mount an actuator on to a manifold
2) The wiring process for the Smatrix Pulse Controller

Thank you.

That's relatively straightforward.
Don't suppose you can show us how to wire the 2 port valve, pump and boiler call can you? Wiring a standard s plan to a normal central heating system is a doddle but how do you incorporate that to your system?

In the manifold cupboard there is a dedicated actuator for my sunroom. However, there was no thermostat installed in the sunroom. Therefore the sunroom temperature is controlled by the thermostat in the adjoining living room. This is fine when the double doors are open between both rooms but not so when the doors are closed and I do not want the sunroom heated. What can I do to trick the sunroom actuator into thinking the room has reached the desired temperature and to shut off? Would really appreciate advice please.

How do you take the wires out of the box when you want to replace one?

[@stuartwebb1521]

How do you remove the wires from the circuit (to remove a dud acuator)? There is a small little peg next to the connecting wire, but I can't figure out how to withdraw the wire.

If the wiring access from the actuator to the panel is difficult - is it acceptable to cut the cable and make a join/junction box to fit a new actuator head?

Our Underfloor heating specialist commented I can’t see any issue myself as long as they don’t exceed the recommended length which is printed in the tech details of each manual.

How do you pressure the underfloor heating? With the flow and returns or place cold into manafold?

Hi, I need to replace an actuator connected to my Smartrix Controller. I have a replacement. Can I disconnect and connect the new without powering down the Smartrix controller? I am afraid the settings will be lost if I power down the Smartrix.

What's the meaning of 2 access points for channel 1 and 2? Can you have 2 actuators connected to one channel, point a and b, to control 2 seperate rooms?

Or you can control the two loops of a larger room with a single thermostat. Since the length of each pipework loop is limited because of factors like water pressure, temperature, sometimes you need to use two or more loops for the same room.
