Euroster 11M thermostat for circulator and three-way valve

EUROSTER 11M is a modern microprocessor controller for controlling heating systems with three-way valves with limit switches. Virtually all valves with 230V 50Hz power supply are supported. Depending on the setting, it can control the inlet water temperature or the return water temperature. The unit can also control the operation of the heating system circulator and switch it off when the boiler is switched off. PI control allows more precise and faster control of the heating system water temperature. EUROSTER 11M can be connected to room thermostats equipped with a voltage-free NO (normally-open) output (all EUROSTER thermostats have this type of output).

EUROSTER 11M has two operating modes: it can control the water temperature at the inlet to the heating system (e.g. floor system) or the boiler return water temperature. The instrument compares the set and actual temperature. If the difference is greater than half of the set hysteresis, the valve opens/closes slowly, thus achieving a smooth change of the heating water temperature in the controlled circuit. The opening/closing speed of the mixing valve depends on the value of parameter 3 (dynamics).

The EUROSTER 11M is equipped with an ANTYSTOP system that protects the pump rotor or valve from clogging during inactivity.

Advantages of EUROSTER 11M:

• Selectable hysteresis
• Clear LCD display - backlit
• Temperature probe correction option
• Manual pump switching option
