1. CHARACTERISTICS

• 4 different programs for each day of the week (28 different ranges and

temperatures altogether). Time programming with 10 minutes accuracy.

• Designed to operate in heating or air conditioning systems.

• Temperature measurement range: 0-50 °C, resolution of 0.1 °C.

• Temperature control range: 5-45 °C, resolution 0.2 °C.

• Hysteresis selectable from 0.5 / 1.0 / 2.0 / 4.0 °C.

• PI - system for heating curve optimization.

• Sensor calibration: from -4.0 °C to 4.0 °C, step 0.2 °C.

• Program copy function.

• Large, clear backlit display.

• Temporary temperature change - the controller instantaneously maintains the

preset temperature until the next program starts.

• Holiday mode - the controller maintains the preset temperature for a selected

time up to 99 days.

• Settings lock - the option to change parameters is blocked. This mode is intended

for offices where only 1 person is entitled to change the settings.

• No heating, i.e. the Anti-freeze mode - the mode of heating in which the

controller maintains the lowest possible and safe temperature (5 °C); in air

conditioning mode the cooling device is disabled.

• Operating time counter of the heating / air conditioning device - maximum

indication 999 hours, with a resolution of 1 minute.

• Ant-freeze protection - the controller turns heating on when the temperature

drops below 5 °C. This function is always active.

• Power supply: 2 AA alkaline batteries.

• Output load: 16 A 230 V AC, 1-pole changeover relay.

• External temperature sensor - NTC 10kΩ at 25 °C.

• Automatic switch between summer and winter time.

• Anti-stop system - the relay is switched on for 1 minute once a week.

• Dimensions (L / H / W.): 132.5 x 85 x 27.6 mm.
