ENGO CONTROLS E901RF Series Programmable Thermostat

Introduction

E901 & E901RF is a weekly, surface-mounted electronic room thermostat intended for home use. It has been designed for control of heating devices (e.g. gas, oil boilers, heat pumps) or cooling devices. It has the function of creating your own schedules. Thanks to the built-in algorithms, it offers much better temperature control accuracy than traditional mechanical thermostats. Please read these instructions carefully before using the device for the first time. The thermostat should use AA, 1.5V alkaline batteries. Put the batteries in the battery compartment located under the flap. Rechargeable batteries are not allowed.

LED indications in the receiver

The status of the receiver is indicated by two LEDs. These are LEDs with the following colors:

– green (upper one),
– orange (lower one).

A detailed explanation of the meaning of the LEDs can be found in the table below:

| DESCRIPTION
---|---
The green LED lights up| The receiver is connected to the 230V power supply.
The receiver can be controlled by thermostat if it is in automatic mode when the right switch is in the AUTO position.
The receiver can be started manually when the right switch is in the MANUAL position.
The green LED flashes| The receiver is in the pairing mode and is looking for a signal from the thermostat (then you must activate the“SYNC” parameter in the thermostat).
The green LED is off| The receiver is disconnected from the 230V power supply or the left switch is in the OFF position.
The orange LED lights up| In automatic mode, the receiver received a heating / cooling signal from the thermostat.
}The receiver was started in manual mode (left ON switch, right MANUAL switch)
The orange LED flashes| The receiver was paired but lost communication with the thermostat due to out of range or low battery in the thermostat. The receiver starts flashing after 40 minutes of time when it does not receive a signal from the thermostat.
The orange LED is off| The receiver does not send a heating / cooling signal.

Manual mode – temperature settings

There are several temperature levels at our disposal. Only one temperature level is realized 24 hours a day in manual mode. You can set a different temperature for each level.

– Comfort Mode – in this mode, the thermostat is to maintain a constant day temperature. When the temperature is set manually, e.g. 23 ° C, the thermostat maintains it until user switches to another operating mode or set a different temperature, e.g. 21 ° C.

– Economic Mode – in this mode, the thermostat is to maintain the reduced (night) temperature. When the temperature is set manually, e.g. 17 ° C, the thermostat maintains it until user switches to another mode or set a different temperature, e.g. 19 ° C.

The values of these temperatures are taken into account in the automatic mode (for the first type of schedule -> see next page).

E901RF pairing process with the receiver

PLEASE NOTE! E901RF THERMOSTAT IS ALREADY PAIRED WITH THE RECEIVER!

If you want to re-pair the devices with each other, make sure that the receiver is disconnected from the power supply, and the switches on it are in the ON and AUTO positions. Then connect the receiver to the power supply and wait for the green diode to glow continuously. Next, move the left switch to the OFF position and back to the ON position with a quick motion. After all, the green diode will start blinking, which will confirm that the receiver has entered the pairing mode.

Press button for 5 seconds.

Use buttons to select SYNC parameter.

Confirm b y button.

Using buttons choose YES and start the pairing process on a new frequency by pressing the button.

The thermostat started to send a signal to find the receiver (the symbol of the blinking antenna) and started the countdown with the number 10 (min). The pairing process may take up to 10 minutes

When the green diode on the receiver lights up continuously, the devices have been paired on a new frequency

The thermostat will display the message „good”, which means that the devices are successfully paired with each other.

The thermostat will return to the main screen.

WARNING! If the green diode on the receiver has not stopped blinking after 10 minutes, repeat the pairing process taking into account the distance between devices, obstacles and interference.
