Deville Wood Pellet Boiler Adjustment

[dirk pitt]

OK, in this case, it is not a heating loop and therefore it is not like the diagram above, or at the moment when your thermovar will close, all the cold water of your circuit, pushed by the hot water coming out of the boiler will sink full pot into the boiler return which is not good.
try to make an exact diagram of where its exactly the thermovar and the circulator in this loop because there, I don't really understand.

[Yacha]

if you take as on the diagram below

me on the heating loop I have a thermovar (in place of your system with the green button) and a circulator on the orange pipe of the boiler and a non-return valve on the input of the pad here I have no cold return in Boiler

by account I did not understand your story of sctoch sa sa m interresse

[dirk pitt]

OK if your circulator is on the orange branch, it is sure that you have to put it a little quick to load the balloon.
the tape on the probe, it insulates it a little thermally so it increases the time it reacts and therefore it increases the hysteresis. Be careful, it also shifts its nominal value a bit so sometimes you have to correct it a little.
for example:
today by setting 65 °, your boiler stops at 65 ° and restarts at 62 ° (3 ° fixed setting)
by isolating it a little and staying at 65 °, it will stop at 67 ° and restart at 60 ° (7 ° hysteresis)

[Yacha]

ok and what is the point of shifting this much?

[dirk pitt]

the purpose of my probe isolation manipulation is not to shift (this is a consequence) but to increase the hysteresis which is not adjustable on this boiler.
generally, increasing the hsyteresis makes it possible to lengthen the boiler on / off cycles. this is even more the case when the values ​​are shifted downwards because the heat losses are lower.
therefore a boiler which starts at 60 ° and stops at 67 ° will have longer and regular cycles than a boiler which starts at 62 ° to stop at 65 °

[Yacha]

hello I dig up the subject a bit, because I need advice on the installation of a simple regulator on my mixing valve the prices that one announces me slows me down a bit, I saw on the net fairly simple regulators which pilot the v3V but here we were yesterday about my stepping motor or all or nothing and I don't understand it too much could indicate a not too expensive rule to install on my install

[dirk pitt]

can you give the brand and reference of your 3-way valve?

[Yacha]

somatherme valves kv 12, 26/34

[dirk pitt]

no problem, it's a motorizable valve.
you just have to buy the engine compatible with the regul.
most motors and regulators have an on / off front / rear motor. that means that they are driven by opening or closing pulses.
what did you find as a regul to ride on.
you need an independent regulator with an external probe.

there are the regul sorel

there are also the regul siemens sigmagyr

[Yacha]

thank you for the answer
I found her http://www.nideck.com/index1.html
but I have no response from the manufacturer
I look at the addresses you gave me
