    1.USE: The SOLARTHERM 17, 28 KDZ 25 unit is a modern compact consumer appliance which ensures the heating of premises and, at the same time, the heating of utility water (hereinafter referred to as TUV) using a condensing boiler. The complete set consists of a well-established Therm 17 or 28 KDZ condensing boiler, TUV accumulation storage tank with a volume of 250 l, solar system pumping group, solar regulator, expan- sion tank, thermostatic mixing valve and all other parts necessary for the correct and problem-free operation of the whole system.

    4. PRODUCTION INSPECTION All parts of the consumer appliance are checked and adjusted before completion by the producer. Each boiler is tested for tightness of the water circuit, tightness of the gas circuit and tightness of the solar circuit. At the same time the activity of regulation and safety elements is checked and adjusted. 5.

For high-quality regulation it is possible to use the intelligent programmable regulator Honeywell CR04, THERM RC 03, or regulator PT59, which using interface IU02 communicates with the microproces- sor of the boiler automated system.

  • Page 15: Commissioning

    Recommendation: We recommend controlling the operation of the separate boiler (without the option of equithermal regu- lation) at least by using a simple spatial thermostat. The spatial temperature is time stable and keeps the boiler in longer operating regimes. The setting of the boiler thermostat is recommended in transient periods (autumn, spring) at 60°C, in winter periods up to 80°C.

The boiler is ignited for starting output (10 seconds after ignition of the boiler) and consequently the output of the boiler is increased to the maximum to increase the output temperature to 80 °C as quick as possible. This temperature is kept by the regulation of the output of the PID type. During the heating of the storage tank, the thermostat disconnects and the boiler interrupts the burning.
