  • Page 60 DTC 100/4 TD DEAR CUSTOMER Congratulations ! You have bought a DTC 100/4TD differential thermostat, manufactured according to the latest quality and safety standards. It is made according to the state of art and efficiently utilises solar energy or alternative sources for domestic water heating. It is designed in compliance with strict criteria and requirements of West Eu ro pean mar kets and enables efficient use of solar energy which enables con sid erable savings of other sources for domestic water heating.
  • Page 61 DTC 100/4 TD GENERAL DTC 100/4TD is a microprocessor aided double differential thermostat, designed for heating of domestic water from two heating sources (collectors, boilers, heat pumps,...), using its logic of additional energy source switching on (boiler of central heating system). The thermostat controls two pumps or two motors actuated ball valves (EMV 800...) and one burner or electric heating element.
  • Page 62 DTC 100/4 TD When pump operates for primary heating circuit (collectors), operation of after-heating circuit and burner of boiler or electric heating element is prevented. This assures maxi mum energy savings during summer seasons and is also the main role of solar sys tems. The set comprises four sensors (T1, T2, T3, T4).

  • Page 65 DTC 100/4 TD THERMOSTAT REGULATION The following settings are performed with keys situated under display: Maximum temperature in hot water tank. Difference of collector circuit. Difference of after-heating circuit (boiler). Setting two working regimes - C.n.b and C.d.t. Collector circuit operation switching off with automatic operation of after-heating circuit.
