2.4 Remote Control Input (TH148LE-P only)

The TH148LE-P thermostat has an input to which a CT240 tele- phone controller (optional) or any other remote control system (e.g., home automation) can be connected. When the input receives a

12-VDC signal, the thermostat switches from its current mode to the unoccupied mode and vice versa when the signal is removed.

The unoccupied mode can be used to re-adjust the temperature to save energy when you are away for an extended period of time. To set the unoccupied mode temperature, see section 4.

2.4.1 Connecting to CT240

Connect TH148LE-P terminals UN and UN to

CT240 terminals A and C (no polarity to observe).

2.4.2 Connecting to a Home Automation System

Connect TH148LE-P terminals UN and UN to a 12-VDC circuit as shown.

2.5 Setting JP2 Jumper

The jumper specifies how the fan will operate when it is placed in automatic mode.

TH147-P, TH148LE-P specifications

Aube Technologies, a prominent name in heating control solutions, offers innovative products that cater to residential and commercial needs. Among their notable offerings are the TH148LE-P and TH147-P thermostats, designed to enhance energy management and ensure optimal comfort.

The Aube Technologies TH148LE-P is a programmable thermostat that stands out with its ability to manage electric heating systems efficiently. It features a sleek, modern design that fits seamlessly into any decor. A key characteristic of the TH148LE-P is its adaptive intelligence technology, which learns the user’s schedule and preferences over time. This feature allows the thermostat to preheat or cool the space before a designated time, ensuring comfort while optimizing energy consumption. Additionally, the TH148LE-P comes equipped with a large, easy-to-read digital display, making it user-friendly for all ages.

On the other hand, the TH147-P model is a more straightforward, non-programmable thermostat. It is ideal for users seeking a simple solution without the complexities of programming. This model provides reliable performance with precise temperature control, ensuring the desired ambient conditions are consistently maintained. The TH147-P is known for its durability and energy-efficient operation, making it a practical choice for various settings.

Both models utilize advanced technologies that promote energy savings. They feature a built-in countdown timer that ensures the heating or cooling systems operate only when necessary, further reducing energy waste. The compatibility of these thermostats with a wide range of heating systems, including baseboard heaters and radiant floor heating, adds to their versatility.

For energy-conscious consumers, the Aube Technologies TH148LE-P and TH147-P are equipped with features that promote sustainability. The ability to monitor energy usage helps users make informed decisions about their heating habits, resulting in lower utility bills and a smaller carbon footprint.

In summary, Aube Technologies’ TH148LE-P and TH147-P thermostats are exemplary products that reflect the company’s commitment to innovation in temperature control. With their state-of-the-art features, user-friendly designs, and energy-saving technologies, they provide excellent solutions for maintaining comfort in any environment, making them a smart investment for anyone looking to optimize their heating and cooling systems.
