“Merchants” take advantage of this to the full, flooding the market with all kinds of “stray” and “gadgets.” Among them are useful, but still useless much more. Even worse: there are those who put it on a car is dangerous. But today we are testing on Viva 2114 Niva a seemingly useful thing - an advanced electric heater tap. Anyone who has dealt with an old crane in the Zhiguli and Niva fields will be interested in the results: maybe after thirty-five years of research, a decent solution has been found! How many improvements the notorious faucet has already undergone, and the heater control scheme has remained the same: to select the optimum “blast” temperature in the cabin, you need to move the faucet control lever, as well as the air supply lever. Troublesome, and distracting the driver.

A company called the Ryazan Plant of Ceramic Metal Devices offers another scheme for maintaining the optimum temperature. The SUOS-1 device (interior heater control system) consists of a control unit with a regulator and a temperature sensor, a functional unit and a distribution valve (see photo above). The latter must be cut into the gap of the pipe connecting the coolant pump to the heater radiator. The air temperature is measured by the sensor and reported to the control unit.

The traditional lever here was replaced with a potentiometer (photo 1). Rotating its handle, select the desired temperature in the cabin - this "economy" manages the functional unit.

And let's try all this in action!

On Niva, we conveniently placed a distribution valve in the engine compartment (photo 2). To ensure the crane is in an optimal position, the nozzle had to be shortened a little. By the way, when installing the crane, we did not even drain the coolant, as is customary - we did everything quickly, losing it very little. The functional block (photo 3) was fixed in the engine compartment on a standard stud.

Having added as much coolant as needed, they started the engine and warmed up. We turn the regulator knob (see photo 1) to the leftmost position, in which the heater must supply cold air to the passenger compartment - it wasn’t there, the air is already sultry! It turns out that a closed tap lets fluid through. Okay, let's try to warm it up again - turn the handle clockwise. Here it is - please! The cabin was like in the Sahara. Let's turn it again counterclockwise … The temperature drops slightly - much slower than with a working native tap!

The reason should be clear. In order for the air temperature in the cabin to drop faster, the jet entering it must be really cold, otherwise it will take a long time to wait! The sophisticated system responds to commands with a considerable delay, but the regulator does not have a scale, the temperature must be selected using the “spear method”, which makes life more difficult for the driver.
