## Description

Dual controller for temperature and humidity, allows simultaneous control of two equipment through two separate outputs of up to 10A, 12VDC power supply with direct output on the active channel, heating or cooling mode and humidification or dehumidification by setting start/stop thresholds, independent calibration for temperature and humidity, clear display with two different color screens.
W1099 thermostat that allows the control of two devices simultaneously. It has two sensors, one for temperature and one for humidity, which can control two individual outputs. It is powered by a 12VDC DC source. The outputs directly show the supply voltage when the thermostat activates the respective channel.
Both temperature and humidity can be calibrated.
The thermostat can operate in heating or cooling mode, depending on the equipment connected to it, meaning that the start temperature can be set lower or higher than the stop temperature. The same goes for humidity, meaning that a humidifying or dehumidifying equipment can be connected.
The display shows temperature and humidity on separate displays that have different colors (red temperature, blue humidity).
The thermostat has a single, common connector for temperature and humidity, with no additional connector available for probes.

Connection instructions:
Instructions for use:
Set the start temperature:
Press the Up button ① once to display the start temperature.
Press and hold the Up① button for about 3 seconds until the start temperature number flashes. The required temperature can be set with the Up① and Down① buttons.
Set the shutdown temperature:
Press the Down button ① once to display the shutdown temperature.
Press and hold the Down① button for about 3 seconds until the stop temperature number flashes. The required temperature can be set with the Up① and Down① buttons.
Set the starting humidity:
Press the Up button② once to display the starting humidity.
Press and hold the Up① button for about 3 seconds until the start humidity number flashes. The required temperature can be set with the Up② and Down② buttons.
Set the shutdown humidity:
Press the Down button② once to display the stop humidity.
Press and hold the Down② button for about 3 seconds until the stop humidity number flashes. The required humidity can be set with the Up② and Down② buttons.
Temperature (humidity) correction:
Press the Up① and Down① buttons at the same time for 3 seconds to display 0.0, then set the value by pressing the Up① and Down① buttons.
Positive value = Measured value + Corrected value (Humidity correction is the same method, pressing the Up② and Down② buttons. )
Reset:
When the power is on, long press the Down① and Down② buttons at the same time for 3 seconds. The reading shows 888, and then the controller automatically jumps to the detected temperature (humidity).
Operating modes:
HEATING MODE | COOLING MODE
START TEMPERATURE < STOP TEMPERATURE | START TEMPERATURE > STOP TEMPERATURE
Heating mode is established if the start temperature is set lower than the stop temperature. The same setting is valid for the Humidity function. | Cooling mode is established if the start temperature is set higher than the stop temperature. The same setting is valid for the Humidity function.
