power conditioning for boiler and controls

Constantin

Unlike surge protectors that are based on metal-oxide varistors (MOVs), that baby has all sorts of heavy-duty hardware to absorb strike energy and ground it out. Check out their technical information section, I was certainly impressed.

power conditioning for modern equipment

My stereo has a nice UPS. My computer has a nice UPS. My modern, circuit-board-rich boiler and tekmar control package pull straight from the panel. Hmmm....

I don't think a UPS is really necessary or practical (correct me if I'm wrong), but protection from spikes and related nastiness seems indicated.

What should I be looking for/at?

Thanks.

Constantin

For that Vitodens project in ME that I helped with,

I installed a brick wall on the advice of Perry. That keeps the spikes out (which have disabled many other things, the owner told me). Behind the brick wall, I have a standard 700VA Smart UPS from APC that puts out sinusoidal power covering brownouts as well as a bridge until the genset comes on if the primary power fails altogether. Between the two devices, I hope there will be no power related issues.

Same here on the Brick Wall

but I elected not to install a UPS. While I could figure it out around it, I was concerned that a UPS might defeat the LWCO and other safeties. (The LWCO was installed rather high in the safety circuit.)

The Brickwall surge suppressors are now our specification standard for protecting delicate electronics.

Constantin

Good point!

I had the installers in ME wire the Vitodens and its LWCO completely downstream from the power supply. The Vitodens was fitted with a plug, which can go into the APC, the brick wall, or directly into the outlet. Makes replacing components that much easier if they fail.

However, if you consider the many exciting ways that consumer products can fail... I mean, the brick wall may protect the mains, but what about all the other wires? Consider, for example, how easily a lightning strike could find a external temperature sensor... where was that board again? :-P

been considering this

thinking about getting one of these to run my boiler during power outages: Noma Backup Power

I already have a Sy Com whole panel surge protector installed.

back up power

I've been considering getting a ,Noma backup power box from Canadian Tire. (not sure if you have one where you are.) To run my boiler through power outages.

I already have a Sy Com whole panel surge protector.

We to use UPS and surge protectors.Be careful.On some boilers you may create a Problem. HM

Not sure about UPS's, but...

Recommending whole-house surge supressors for years. They protect from just about anything short of a direct hit by lightning. Leviton and Square D make them, and they connect to the main breaker box. They protect every circuit in the house, and since just about everything is microprocessor based today, they just make sense. They are usually installed by a licensed electrician.

Derheatmeister

Bill, on some Boiler the software will lose the "Handshake" and Lockup if you use a surge protector/Ups. HM

Derheatmeister

Bill,to add to that prev. post it is a Honeywell control on a mod-con boiler that will lock up ! They did however fix the problem with a "power delay Relay".Richard from Heatmeister..

Derheatmeister

Why will the LWCO be a problem with a UPS? HM.

Constantin

It depends where the LWCO is wired into the circuit

You don't want a situation where the LWCO trips but cuts power "upstream" of the UPS. In that case, the UPS keeps the boiler going even when the boiler should be shutdown on safety.

If I were to install a UPS, etc. I would install it at the breaker box in the house to ensure that all circuit disconnects / interlocks downstream from it remain effective. Then label the UPS with big letters along the lines of "EMERGENCY POWER FOR HEATING SYSTEM" put a note in the circuit breaker panel, and put a note on the boiler too.

My installer put a service switch for all boiler / heating system power next to the boiler, which makes servicing the thing safely that much easier.

Derheatmeister

Well yes that is a no brainer,Incomming power is to be UPSed or Surge protected. but if one use's a UPS with a Viessmann That is OK (they do not approve of it) but with a Triangle's Prestige that is not,it can create problems.Heatmeister.

Surge Suppressors

Bill - My electrician - a good technician who I respect, suggested that my suppressor was most likely bad. He claimed that they fail and there was no way to know if they were still protecting the equipment.

I took his word and had him replace mine but the new one has no indicator on it either.

We live in an area with heavy electrical storms and it is a source of concern.

I use "add on" surge suppressors and UPS also where needed. On my Knight I'm depending on the main surge suppresor.

Brick Wall

Pretty impressive -

I'll try one

great stuff

Great material in this thread. Thanks!

Approval

HM Viessmann does not approve of a UPS?

jp_2

UPS & solo?

what kind of problems are you talking about?

Al Corelli_2

That canadian Tire Box...

Is the large one 1800 VA?

If it is 1800 volt/amps, then I already have an old APC that I can use.

Didn't know the ratings played out as in the canadian Tire brochure.

Thank you.

I Installed a 11/44 in a PV/Generator situation 3years ago and was taking to viessmann about it (sine wave). They did not approve of anything to go with this situation ,I did use a Good UPS and it's had no Problems ever. HM.

Derheatmeister

NO more Problems after i installed the "Power Delay Relay Kit" which is now Integrated into the 08 models. NOT on all of my installs, but on some, the boiler would just lockup and give me a E code ,it was locking up because it would get a power failure /Spike ,and the Software would lose it's "Handshake".UPS/Surge protector's did not work in this situation. But Triangle is a good company and they provided the parts to fix it, the Power delay Relay which delays to power to the boiler of 3 Min upon Power restore, work's great. HM
