Thermostat 230V ZFX-ST3012
PRODUCT PARAMETERS AND FEATURES
These are two independent thermostats with separate sensors in one controller.
The regulator is designed for automatic temperature control in two places and devices.
Simple and intuitive operation.
The device has a built-in memory of settings. The thermostat does not need to be reprogrammed when power is disconnected.
Clearly visible LED diodes indicate activated relay and activated alarm.
the device has an alarm for exceeding the lower or upper temperature limit.
The alarm is signaled by a sound and a display plus a flashing signaling diode.
Input voltage (supply): AC 230V, the thermostat does not require power.
Relay contacts load capacity: 5A at AC 230V
Temperature measurement: -50°C - +110°C
Temperature measurement resolution: 0.1°C
Temperature refresh rate: 0.5s (very fast)
Temperature measuring probe: waterproof (stainless steel)
Sensor used: NTC10k/343S
The length of the cable with the probe: 95cm (we have longer ones on offer).
The length of the other wires: about 20cm
Probe diameter: 4mm
Probe length: 20mm
Displays: 2x LED 3 digits
Display color: red
Signaling LED color: green/red (relay/alarm)
Housing dimensions without fixings: 76 x 55 x 31mm
Spacing of mounting holes: 88mm
Working temperature: 0°C - 50°C
Weight: 100g

User manual
Thermostat 2 ("up" and "down" buttons under the right display) is programmed in the same way as thermostat 1 ("up" and "down" buttons under the left display).
Thermostat 1 temperature setting:
Press SET once, and then use the "up" and "down" buttons to set the temperature (holding the button down speeds up the temperature change).
Thermostat 2 temperature setting:
Press SET twice, and then use the "up" and "down" buttons to set the temperature (holding the button down speeds up the temperature change).
Thermostat 1 MENU:
Press SET once and then hold SET for 2 seconds to enter MENU.
Thermostat 2 MENU:
Press SET twice and then hold SET for 2 seconds to enter MENU.
Using the "up" and "down" buttons, select one of several functions available in the MENU.
MENU (setting ranges in brackets):
HC - Heating "H" / Cooling "C".
D - °C difference 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 - correction (calibration) of temperature indications (from - 10°C to 10°C).
PT - relay activation delay (0-10min)
Press SET to select the desired function, then use "up" and "down" to change the value.
Press SET to return to function selection.
Always after 5 seconds of inactivity (no matter where in the MENU), the device saves the settings and returns to the temperature display.
A flashing red LED means the PT delay time is counting down.
