How to apply the settings

Set the temperature point set to disconnect and connect the relay

Buttons number 1 are related to setting the start time and temperature relay step. The ˄ button is for setting the starter temperature or connecting the relay and the ˅ button is for setting the step temperature or disconnecting the temperature relay. Each time you press these buttons, the values ​​set by the user are displayed. Now to change the button settings Hold the starter temperature setting for a few seconds until the seven temperature-related segments flash. After the number flashes, set the starter temperature to the desired temperature with the number 1 buttons. After setting the starter temperature, wait a few moments for the device to automatically save the changes. Do the same process to adjust the step temperature.

Setting the humidity point set to disconnect and connect the humidity relay

Buttons number 2 are related to setting the start time and step of the humidity relay. The ˄ button is for setting the humidity of the starter or the same as connecting the relay and the button است is for setting the humidity of the step or disconnecting the humidity relay. Hold down the starter humidity adjustment button for a few seconds until the seven humidity segment flashes. After the number flashes, adjust the starter humidity to the desired humidity with the number 2 buttons. After setting the starter humidity, wait a few moments for the device to automatically save the changes. Do the same process to adjust the step moisture.

Calibrate temperature and humidity values

Press the number 1 buttons at the same time until the temperature number flashes. After flashing, calibrate the temperature with the same keys. Press the number 2 buttons at the same time until the humidity number flashes. After flashing, calibrate the humidity with the same keys.

How to apply the settings

Adjust the disconnect and reconnect temperature of the value by pressing and releasing the SET button once. The low number, which is the user’s set temperature and is indicated by the seven blue segments, flashes. Then the value of this parameter can be increased and decreased with both buttons. Use the ‘C /’ F button to switch between Celsius and Fahrenheit. This thermostat has 9 functions P0 to P9. Hold down the SET key for a few seconds until P0 appears. Release the key and then move between functions each time you press the SET key. To set each of these 9 functions, hold down both buttons simultaneously until the numeric value of the corresponding parameter flashes. Then increase and decrease the numeric value of the parameter with the up and down buttons.

Introduction of functions

P0: C (cooling) H (heating)

P1: Adjusts the hysteresis temperature value

P2: Limit the set point by setting the maximum set point

P3: Limit the set point by setting the minimum set point

P4: Calibrate the current temperature

P5: Set the delay time in connecting the relay if the current set point and temperature are equal

P6: Enable or disable P2 and P3 functions

P7: Change the unit of measurement from Celsius to Fahrenheit and vice versa

P8: Enable or disable factory settings

Introduction

In addition to displaying the temperature and temperature regulation, the JBH macro thermostat is able to control the temperature in both cooling and heating operating modes based on the user’s adjustable temperature. In this way, if the set temperature is set higher than the current temperature, the device automatically enters the heating mode and the heating LED lights up, and vice versa, if the set temperature is set below the current temperature, the device automatically enters the cooling mode and The cooling ID lights up.

How to apply the settings
Set the setpoint temperature for disconnecting and connecting the relay by pressing the SET button for 3 seconds and
Let go. The low number is the same as the user’s set temperature, which is marked with a blue color
Becomes. Then with both up and down buttons, the value of this parameter can be increased and decreased. This thermostat
It has 9 functions P0 to P8. Hold down the SET key for 10 seconds until P0 appears. Release the key
And then move between functions each time you press the SET key. To quantify any of these
9 Functions Increase and decrease the numeric value of the parameter with the up and down buttons. To store prescriptions
Hold down the SET key for a few seconds.

Introduction of functions
P0: Cooling (H) Heating (C)
P1: Adjust the value of the differential temperature) for example if you set the Pointe set number 25 degrees in heating mode and
You have set the differential temperature to 2 degrees and the ambient temperature is 20 degrees, the relay is connected to increase the temperature.
2 + 25. After reaching the temperature of 27, the relay is disconnected and in case of disgust, the temperature drops below 25 degrees,
This cycle is repeated. In general, the eco-thermostat constantly maintains a temperature between 25 and 27.
P2: Limit the set point by setting the maximum set point
P3: Limit the set point by setting the minimum set point
P4: Calibrate the current temperature

P5: Set the delay time in connecting the relay if the set point and current temperature are equal (for the compressor,
Refrigerator and … (
P6: Set the current temperature limit display to on and off
P7: Lock setpoint settings
