Sunvic tlx room thermostat sunvic domestic controls electromechanical range for light to medium duty applications. Three-port valves operate in a similar manner but the wiring is different and some valves are never installed properly by builders and plumbers in the UK. More photos are here. Design collections. Sunvic tlx tpi cont large dig disp Sunvic. It has a different make of microswitch - but these very rarely gave problems anyway. These valves are not sold only under the Sunvic name. Supplying 'live' to where the orange wire from the valve was connected generally enables the boiler to light up and the pump to operate whatever type of valve has been fitted, but there are issues of how hot each circuit will get if it is not properly controlled - so turn down the main boiler thermostat to about C. All our sunvic domestic controls products are genuine branded goods.

I would use you again.
Some evidence has been collated showing the degree to which the micro-switches often used within motorised actuators may overheat and the propensity of the circuit boards within the 'new' Sunvic designs to explode.

Sunvic Szmv Momo 15mm 2 Port Valve. Ideally, a diode would have been incorporated into the pcb design: this 'afterthought' is hardly an advertisement for quality manufacturing. Both types seem to fail in the same way - so a specific design or manufacturing problem seems to be ruled out. Sunvic Tlm Frost Thermostat. |
Motorised Ball Valve Actuator for 2 Port Spring Return Valve - SZ Actuator for use with Type ML/EML 2 port motorised valves; Normally closed when not.
These all have a similar design of electronic circuit and regularly fail in a similar manner. It is made live for dhw via the cylinder thermostat. Sunvic appear to have changed the capacitors to nF to try to avoid premature failures but to little avail - because whole idea of using X2 capacitors to drop mains voltage may be suspect: a particular problem may be high temperatures of operation and frequency of thermal cycling.
Electromechanical range for light to medium duty applications.
Here are some failed capacitors, together with a couple of faulty microswitches. In particular, the internal circuitry of the SD and related 3 port designs is quite complicated and many faults stem from sticking motors and gearboxes. We keep you informed of the progress of your order, good or bad news.

Heating System Supplies. Sunvic tlx control large dial Sunvic. In addition, check that the system really is 'dead' after removing the fuse - I have known houses in which live and neutral lines have been reversed even at the main distribution board fusebox!
If the contact points were the cause of the overheating because of high contact resistance then discoloration would be expected primarily close to the points - yet here it is just as bad on the left hand side. However, it is also necessary to 'con' the boiler into thinking the valve actuator is still in place and ordering heat.
Sunvic Szm Actuator. Sunvic Tlm Frost Thermostat.
It is a cheap way to produce low voltage DC if only a low current is required. These all have a similar design of electronic circuit and regularly fail in a similar manner.
Initially, it was devoted only to the 'new' designs of actuators utilising electronics in lieu of the more conventional spring return mechanisms and indeed the new designs did, in theory, offer quite a few advantages. Invensys Valves and Actuators.
