TB-- PAC / TB-- PHP

pressing UP and FAN buttons simultaneously or changing the setpoint will override the timer for 1 cycle.

Minimum on Timer

Once the equipment has turned on, it will remain on for a minimum of 3 minutes regardless of demand. However, the equipment can turn off in less than 3 minutes if a change in setpoint, or a change in mode occurs.

Staging Timer

If the thermostat is a heat pump model, it has 2-stage heat capability. In normal operation there is a 15-minute delay between the first and second stages of heat. The Y output will energize first, then 15 minutes later, W is allowed to come on if the thermostat determines it is not satisfying the demand.

However, if the heating demand is greater than 5_F/3_C, there will be only a 30 second delay before bringing on W.

Auxiliary Heat Indicator

When operating a heat pump and either auxiliary heat or emergency heat is active, an LCD display icon indicates this condition.

A07821

Error Messages

If the room temperature sensor fails, two dashes (--) will appear in the temperature display and all heating and cooling outputs will be turned off. The thermostat must be replaced.

If the internal non-volatile memory fails, E4 will alternately flash with the temperature on the display and all heating and cooling outputs will be turned off. The thermostat must be replaced.

Step 5 — Check Thermostat Operation

Fan Operation

1.Press FAN button. This will start continuous fan operation. FAN ON icon will turn on.

2.Press FAN button again. This will stop continuous fan oper- ation. FAN ON icon will turn off.

Heating Operation

1.Press H/C button until HEAT is displayed.

2.Press UP button until LCD readout reads 3_F/2_C above room temperature. Press UP and FAN buttons simultan- eously to defeat timers. Heating system should begin to op- erate immediately.

3.For HP thermostats only, press H/C button until EMHT (emergency heat) appears. Press UP and FAN buttons sim- ultaneously to defeat timers. Emergency heating (W is ON, Y is OFF) should begin immediately.

Cooling Operation

1.Press H/C button until COOL is displayed.

2.Press DOWN button until LCD readout reads 3_F/2_C be- low room temperature. Press UP and FAN buttons simultan- eously to defeat timers. Cooling system should begin to op- erate immediately.

TB-PAC, TB-PHP specifications

Carrier TB-PHP and TB-PAC are effective solutions designed to meet the demands of modern heating and cooling applications. These units offer impressive performance, energy efficiency, and innovative technologies, making them a favorite choice for residential and commercial spaces.

The TB-PHP is a heat pump system that provides both heating and cooling capabilities, offering an economical solution for maintaining comfort throughout the year. One of its key features is the inverter technology, which allows the system to adjust its output based on current load requirements. This results in energy savings and enhanced comfort levels, as the temperature is maintained consistently without the fluctuations commonly associated with conventional systems.

Another notable characteristic of the TB-PHP is its exceptional seasonal efficiency rating. With its advanced design, this heat pump offers high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings, ensuring that users benefit from lower energy bills while also reducing their environmental footprint. The unit's low noise levels enhance its appeal, making it suitable for residential spaces where quiet operation is valued.

Complementing the TB-PHP is the TB-PAC series, which is a packaged air conditioning system designed for easy installation and operation. The TB-PAC features a compact design that allows for space-saving installation, making it ideal for urban settings or properties with limited outdoor space. The robust construction of the unit promotes durability, ensuring that it can withstand a range of environmental conditions.

In terms of technology, both the TB-PHP and TB-PAC are equipped with intelligent controls that facilitate easy monitoring and management of system performance. Users can access diagnostics, settings, and maintenance alerts, contributing to effective system operation and longevity. Additionally, the units support various refrigerants, adhering to environmental standards while maximizing efficiency.

Overall, the Carrier TB-PHP and TB-PAC are distinguished by their advanced technologies, energy efficiency, and user-friendly features. The combination of innovative engineering and commitment to sustainability positions these systems as top contenders in the heating and cooling market, providing comfort and reliability for users across different environments.
