From the apartment in his house. Inzhenerki: boiler room, nuances

Adjustment of control automatics in the combined (gas and electricity) heating

The first caveat.

In the last of the All like clockwork vice versa (before the last photo).

Went to work, come the evening. While unloads, the wife of the house and the noise: the house is cold, warm the battery, but not hot, what should be. So, it is necessary to understand, and went. I went to the boiler room, like all the noise. As in such a situation, understand? Right, are beginning to touch, where hot where it is cold. As expected? Boiler pump pushes the hot medium circulation pump group picks up and pushes inside. Tank line comes the cold and into the boiler.

Circle by operating the electric:

Circle at the gas:

What actually.

Runs gas boiler, with hot boiler outlet reached the pump group, like the outlet pipe of the circulation pump also become warm and then stop - off gas. I try at the entrance to it - hot tube. How so? The house is gone, and has already returned. Multiple starts and stops, it became clear that the hot does not go into the house and comes back.

Driving such.

Hot in the house is not (something slips on leftovers), and right from the pump group back. Naturally, the boiler, hot defining inlet, turns off. Needless switched it on for long, and in the off state for a long time - until hot to cool in a small circle.

At the same time, it was hot in the tank line and an electrical output (heating elements do not work). It became clear that the fluid circulates in two circles with the point of contact in the pumping group.

I called Dima and videoconference begin to understand. At first I figured out for myself that in this group there is a collector, which provides reverse coolant pressure equalization. But he is alert, where the accident? Why was not there before? If the valve at the entrance to close the electric - everything is OK. You open again return pipes. Well, what's wrong?! I get tired and Dima, and he with me: Turn there, check here and so on. As a result, Dima really somewhere to 23.00: you come, we understand, and went to sleep (shut down).

Why electrically at night and checking such dances with a tambourine there?

I sit, so where's the next 23.00.

At the appointed time, the electric click, gone. Torch gas asleep. Begin to touch the pipe... It is not yet clear, and suddenly - stopped the gas. T. e. display lights up as it should, but it died down. What was quiet? Let's restart. Waiting. Exactly two minutes after the contact has opened, turned off (v) the pump and the gas boiler to the gas pipe begin to cool. A ring electric works very well. Checking the temperature sensor is an electrical discontinuity. No, it pump runs constantly. T. e. functionally laid:

• in the gas by opening the external sensor is extinguished torch and after two minutes the pump is switched off. When the sensor circuit and the torch and pump are started simultaneously.
• in the electric pump runs constantly, the heating elements are switched off only.

Generally clear. Boilers can operate independently, without pumping group, in relatively small houses. The electric is provided that drives the pump fluid into a permanent system. The gas is incorporated: the pump turns off after two minutes. Not ready to argue that it is true that there is, perhaps, the function is configured in a stealth mode, I do not know. I work with a given.

When running the electric boiler, its pump circle gas trapped its inoperative pump.

When the working gas, the range of electric also active, whereby:

boilers pumps on opposite sides of the hot medium is pushed to the input manifold. But from the hot collector output can not leave the coolant more than he can take circulator. At the same time from a cold collector output both pumps draw fluid into different directions, and it is naturally not enough. Vacuum. That accident. The manifold valve opens and hot went to the return line. Moreover, the vacuum so that the network circulation pump almost nothing remains. A return pipe for a hot gas, and disables it. Circle. Heat in the house no.

What should be done? Disable the electric pump. Was bought by the second timer, the pump is connected through it. The time is reduced with the time of the timer on the temperature sensor. Actually all.

The system functions.

Information.

Radio engineer by profession, and in the course of life one way or another worked as an engineer. The fifth group tolerance. Questions of organizational and technical measures... - in my practical functionality. I understand security, as well as running electrical currents and other streams.

Caution not professionals: do not fit, he will.

Rely on the experts, the main thing - not to lose his aptitude. To my Dime does not apply.

Nuance second.

It is connected just with timers. Photo repeat.

I bought the first. It so happened that both channels are working on opening night: in the electric mirror gases. Accordingly, the timer has been set up:

1 period: the inclusion in the 6.00 - off at 23.00. A copy of the seven days of the week.

There was a need to buy a second, to enable the pump from 23.00 to 6.00.

And then he drew attention to the reviews. The main thing at night, when you change the day, it is impossible to set up the continuity of the cycle, will be a gap of one minute - discrete timer. This is not critical, a warning, someone returns.

We must say frankly - instructions for setting the timer is very indistinct.

Bought, I began to adjust:

1 Period: incl. 23.00, Off. 6.00.

Summed up the clock at 23.00 included.

Led watch 5.55, only approx pressed - Switch off. How so? I turn it on.

So, try on:

• 1 Period: incl. 00.00 - off. 6.00 - all ok.
• Period 2: 23.00 On - Off... and here the question. You put 00.00 - the timer does not turn on.

Second attempt:

Period 2: On 23.00 - off. 23.59 - open until 23.59 and off for 1 minute. It starts at 00.00. T. e. what say others.

The Chinese have a different make, but still, the timer with the artificial rupture - this too. So, there is a solution. And it is.

Third attempt:

Period 2: incl. 23.00 - off. "--.--" is not necessary to prescribe off. and a timer included in the new day without opening.

Again, there is a nuance: when you press a button and virtually turns OFF mode. just blink 00.00 and it is confusing. But then you press RESET - resetting and "--.--" - off time is not assigned. If such appointment to enter the new day, where the period does not begin in 0000, and, for example at 1.00, then the timer will turn off at 00:00 and turned on at 1.00.

All life - continuous nuance.

And why?

Some are not appended, others half-taught, beginning to talk and advise, or even impose, the third general, all do not care, pardon the expression, if only poorat ..
