230V Thermostat ZFX-ST3012

230V Thermostat ZFX-ST3012

PRODUCT PARAMETERS AND FEATURES Two independent thermostats with separate sensors in a single controller. The controller is designed for automatic temperature regulation in two locations and devices. Simple and intuitive operation. The device has built-in memory for settings. No reprogramming is needed after power loss. Clearly visible LEDs indicate the engaged relay and activated alarm. The device has an alarm for exceeding the lower or upper temperature limit. The alarm is signaled by sound, display, and a flashing indicator LED. Input (supply) voltage: AC 230V, thermostat does not require external power. Relay contact load: 5A at AC 230V Temperature measurement: -50°C - +110°C Temperature measurement resolution: 0.1°C Temperature refresh rate: 0.5s (very fast) Temperature sensor probe: waterproof (stainless steel) Sensor used: NTC10k/343S Probe cable length: 95cm (longer cables available). Length of other cables: approx. 20cm Probe diameter: 4mm Probe length: 20mm Displays: 2 x 3-digit LED Display color: red Indicator LED color: green/red (relay/alarm) Housing dimensions (excluding mounts): 76 x 55 x 31mm Mounting hole spacing: 88mm Operating temperature: 0°C - 50°C Weight: 100g Pinout description and operating instructions below in the graphics. Operating Instructions Thermostat 2 ("up" and "down" buttons under the right display) is programmed analogously to thermostat 1 ("up" and "down" buttons under the left display). Setting the temperature of thermostat 1: Press SET once, then use the "up" and "down" buttons to set the temperature (holding the button speeds up the temperature change). Setting the temperature of thermostat 2: Press SET twice, then use the "up" and "down" buttons to set the temperature (holding the button speeds up the temperature change). MENU of thermostat 1: Press SET once, then hold SET for 2 seconds to enter the MENU. MENU of thermostat 2: Press SET twice, then hold SET for 2 seconds to enter the MENU. Using the "up" and "down" buttons, select one of several functions available in the MENU. MENU (settings ranges in brackets): HC - Heating "H" / Cooling "C". D - difference °C between the set temperature and the relay activation temperature (1-30°C). LS - low temperature alarm (from -50°C to +109°C). Alarm signaled by sound, flashing red LED and display "-L-". HS - high temperature alarm (from -49°C to +110°C). Alarm signaled by sound, flashing red LED and display "-H-". CA - temperature reading correction (calibration) (from -10°C to +10°C). PT - relay activation delay (0-10min) Press SET to select the appropriate function, then use "up" and "down" to change the value. Press SET to return to function selection. After 5 seconds of inactivity (regardless of where in the MENU), the device saves the settings and returns to displaying the temperature. A flashing red LED indicates the PT delay countdown.
