Mitsubishi Ecodan PAR-WR61R-E Wireless Receiver

The Mitsubishi Electric Ecodan PAR-WR61R-E wireless receiver is a control accessory designed to integrate PAR-WT60R-E wireless controllers into compatible Mitsubishi Electric Ecodan air source heat pump systems. The receiver connects to the indoor unit or the FTC control system, receives commands from paired controllers by radio, and transmits both the commands and the information required to regulate the Ecodan system.

Thanks to its wireless communication at 868.3 MHz, it allows the room controller to be installed without the need to run a control cable to its location. A single receiver supports pairing with up to 8 PAR-WT60R-E wireless controllers, making it easy to create control configurations tailored to the needs of the installation.

Receiver for the PAR-WT60R-E wireless controller

The PAR-WR61R-E works together with the Mitsubishi Electric PAR-WT60R-E wireless controller. The receiver acts as the link between the wireless controls installed in the home and the electronics of the Ecodan system.

Commands sent from the controller are received by radio and transmitted to the indoor unit. This avoids the need to run a control cable to the chosen location for the wireless thermostat.

The PAR-WT60R-E controller is sold separately unless the commercial offer expressly states that it is included as part of a set.

Compatible with Mitsubishi Electric Ecodan systems

Mitsubishi Electric classifies the PAR-WR61R-E as one of the control accessories for Ecodan systems. The official manual includes installation in systems with Hydrobox and Cylinder Unit indoor units compatible with the ATW wireless control architecture.

Final compatibility should always be checked against the specific generation of indoor unit, Hydrobox, Hydrobox Duo or FTC interface used in the installation.

Up to 8 wireless controllers per receiver

A single PAR-WR61R-E allows pairing of up to 8 PAR-WT60R-E wireless controllers. Each controller must be configured with its corresponding address during the pairing procedure.

This capability makes it possible to use multiple compatible controls within the same Ecodan system when the installation and controller configuration allow it.

Wireless communication at 868.3 MHz

The receiver uses a radio frequency of 868.3 MHz to communicate with the wireless controllers. Mitsubishi Electric specifies a maximum transmission power of 10 dBm.

The effective range depends on the building, the position of the receiver and controller, construction materials, and the presence of obstacles or interference. For this reason, the manufacturer recommends carrying out a communication test once the system has been installed and paired.

Powered by the indoor unit

The PAR-WR61R-E does not require batteries or an independent power supply. The receiver is powered directly from the Ecodan indoor unit at 12 V DC.

Mitsubishi Electric expressly warns that the receiver’s maximum voltage is 12 V DC and that it must not be connected directly to a 230 V AC supply.

2-meter connection cable included

The receiver is supplied with an approximately 2-meter connection cable. This cable allows the receiver to be connected to the compatible indoor unit in accordance with Mitsubishi Electric’s installation instructions.

The manufacturer’s dimensional drawing shows an effective cable length of around 1890 mm.

Wall mounting

The PAR-WR61R-E is designed for wall mounting. The package includes a dedicated bracket that allows the receiver to be fixed in the selected position.

The location should be chosen taking into account wireless communication quality and avoiding places exposed to condensation, large amounts of steam, corrosive agents, or environmental conditions outside the specified range.

Compact dimensions

The receiver has a compact format that makes it easy to integrate near the indoor unit:

• Width: 100 mm.
• Height: 80 mm.
• Depth: 30 mm.
• Weight: approximately 150 g without cable.

Status and communication LED indicators

The receiver includes two light indicators that make commissioning and diagnostics easier:

• Green communication LED: shows the status of wireless communication.
• Orange operating LED: indicates operating status and pairing processes.

Through different combinations of steady light and flashing, the LEDs can identify states such as unpaired receiver, paired receiver, active communication, successful or failed pairing process, and deletion of pairing information.

Built-in configuration button

The PAR-WR61R-E has an adjustment button located on the top. This control is used to switch between the operating modes required during setup.

The receiver mainly offers:

• Normal operating mode.
• Pairing mode.
• Pairing information erase function.

Pairing procedure

To use the wireless system, pairing between the PAR-WR61R-E receiver and each PAR-WT60R-E controller is required.

Mitsubishi Electric sets out the general procedure as follows:

• Initially disconnect the Ecodan system.
• Install and connect the receiver.
• Set the corresponding DIP switch on the control board.
• Power the system back on.
• Install the batteries in the PAR-WT60R-E controller.
• Carry out the pairing process.
• Then check the communication quality.

During installation, Mitsubishi Electric indicates that the corresponding SW1-8 setting must be activated on the control board according to the instructions for the compatible Ecodan unit.

Wireless communication test

After pairing the devices, the installer can perform a communication test to verify that the chosen position allows reliable transmission between controller and receiver.

This check is especially important when there are thick walls, metal elements, or other obstacles between both devices.

Option to use the controller as a room sensor

In compatible Ecodan configurations, the PAR-WT60R-E controller paired with this receiver can be used as a room temperature sensor and wireless thermostat.

When the system operates with room temperature control, regulation can use the temperature measured by the controller to manage system operation. The exact configuration depends on the Ecodan controller used.

Operating environmental conditions

Mitsubishi Electric specifies the following environmental limits for the receiver:

• Temperature: 0 to 40 °C.
• Relative humidity: 30 to 90%.
• Condition: non-condensing.

The receiver is intended for indoor environments compatible with these limits and must be kept away from areas exposed to heavy steam, water, corrosive gases, or atmospheres with a risk of flammability.

Package contents

According to the official Mitsubishi Electric manual, the PAR-WR61R-E is supplied with:

• 1 PAR-WR61R-E wireless receiver.
• 1 integrated 2 m connection cable.
• 1 mounting bracket.
• 4 flat-head screws 4.1 x 6 mm.
• 1 installation and setup manual.

The PAR-WT60R-E wireless controller is not included with the receiver and must be selected separately.

Radio equipment compliance

Mitsubishi Electric declares that the PAR-WR61R-E, together with the PAR-WT60R-E, complies with the applicable requirements of Directive 2014/53/EU on radio equipment.
