Thermostat Installation

The thermostat should be located on an interior wall in a larger room, away from supply duct drafts. DO NOT locate the thermostat in areas subject to sunlight, drafts or on external walls. The wire access hole behind the thermostat may in certain cases need to be sealed to prevent erroneous temperature measurement. Position the thermostat back

plate against the wall so that it appears level and so the thermostat wires protrude through the middle of the back plate. Mark the position of the back plate mounting holes and drill holes with a 3/16” (5mm) bit. Install supplied anchors and secure plate to the wall. Thermostat wire must be 18 AWG wire. Wire the appropriate thermostat as shown in Figures 24a and 24b to the low voltage terminal strip on the DXM2 control board. Practically any heat pump thermostat will work with these units, provided it has the correct number of heating and cooling stages. However, using the communicating thermostat (ATC32) is highly

recommended for on-site, easier configuration, monitoring and diagnosis.

CAUTION!

CAUTION! Refrigerant pressure activated water regulating valves should never be used with manufacturer’s equipment.

Notes:

1)ECM automatic dehumidification mode operates with dehumidification airflows in the cooling mode when the dehumidification output from thermostat is active. Normal heating and cooling airflows are not affected.

2)DXM2 board DIP switch S2-7 must be in the auto dehumidification mode for automatic dehumidification

3)DH connection not possible with units with internal pump. Use ATC32U**.

4)Only use ATC Communicating Thermostat when using Humidifier (H Input) with units with internal flow controller.

HEV/H specifications

The Heat Controller HEV/H series represents a significant advancement in heating technology, designed to provide efficient and effective climate control for both residential and commercial spaces. This innovative range of heat pumps combines cutting-edge features with user-friendly functionality to offer a reliable solution for modern heating needs.

One of the standout features of the HEV/H series is its advanced inverter technology. This system allows the heat pump to adjust its output based on the specific heating requirements of the environment. By varying the compressor's speed, the HEV/H maintains a consistent temperature while significantly reducing energy consumption. This not only lowers utility bills but also reduces environmental impact, making it a more sustainable option compared to traditional heating methods.

The HEV/H series is equipped with a high-efficiency heat exchanger, which maximizes heat transfer and enhances overall performance. This component ensures that the system can operate effectively even in colder climates, providing reliable heating throughout the winter months. Additionally, the unit’s low noise operation is designed to maintain a peaceful environment, making it suitable for bedrooms, offices, and other noise-sensitive areas.

Another notable characteristic of the HEV/H series is its smart control features. Integrated with Wi-Fi connectivity, users can conveniently manage their heating settings remotely via a smartphone app. This feature allows for customized scheduling and temperature control, ensuring optimal comfort and convenience. Users can also receive real-time notifications on energy consumption and system performance, enhancing user engagement and control.

The HEV/H series also emphasizes durability and longevity. Constructed with high-quality materials, the units are designed to withstand the rigors of daily use while requiring minimal maintenance. The incorporation of advanced filtration systems helps to improve indoor air quality by capturing dust and allergens, which is especially beneficial for individuals with allergies or respiratory issues.

In summary, the Heat Controller HEV/H series exemplifies modern heating technology with its combination of efficiency, control, and user-friendly features. Its inverter technology, high-efficiency heat exchangers, smart connectivity, and durable construction make it an outstanding choice for anyone seeking to enhance their indoor climate while being conscious of energy usage and environmental impact. Whether for a home or business, the HEV/H series is poised to deliver exceptional heating solutions tailored to diverse needs.
