Therefore, the choice of Taco 007 necessarily need to find out their main characteristics (listed in this and the previous two parts of this article) to be fully aware of its advantages and disadvantages.
It should also take into account that always has a sense of preferred products known company, with well-functioning for years the technology of thermostats and having a reliable system of quality control.
The presence of pre-hydraulic application allows you to reduce the cost of adjusting the heating system.
Practical experience of commissioning of heating systems has proved the need for setting the most simple way, without using special tools and devices, opportunities clearly see the resulting position of the valve; ease of checking and adjusting the settings and at the same time protecting it from unauthorized user intervention.
Taco optimally solve the problem of convenience and reduce the cost of setting up the system and further to protect the settings of valves. Valve RTD-N have the ring of a preset coolant flow, which makes it possible to use one type of valve, a hydraulic system setup to after installation.
Presetting can be selected in the range of numbers on the ring of nozzles from 1 to 7 in increments of 0.5, which gives the opportunity to ask 14 different values for each valve.
The protection of a preset from unauthorized access can be made in two ways. The first – ring preset hidden under installed thermostatic element and is not in sight. To prevent the removal of the thermostatic element used countersunk screw into the connecting nut, which can not be dismantled without special tools. The second – using a special plastic ring, which fixes the preset and simultaneously performs the function of security seals. These two methods can be used together or separately. In case of need for stronger protection (schools, kindergartens and other public buildings), Taco recommends the use of a thermostatic element with protected versions.
The possibility of replacing the seal without draining the water from the pipeline is a requirement of European Standard EN 215. Replacing the seal should be carried out by a simple unscrewing it from the valve body with a spanner. Usually gland changing less than 1 time in 10 years. In addition, installation and commissioning organizations sometimes interested in the possibility of replacing or cleaning the entire Headvalves RT valve without draining the water from the pipeline. Such tools are available in some of the manufacturers. Taco also has a special tool, included in service kit, allowing easy replacement and cleaning Headvalves valve completely without draining the water from the pipeline, on which you installed the RT valve.
The presence of a special version of the RT Taco, adapted to the markets of Eastern Europe and the CIS, due, primarily, the poor quality coolant. Moreover, Western heating equipment is not always possible to use us without regard to national requirements and traditions. Therefore, it is important that controllers have been specially adapted for existing in Canada, heating systems and their operating conditions, have enhanced the design and produced in the country, which focused.
