5 CHECK THERMOSTAT OPERATION

NOTE

To prevent static discharge problems, touch side of ther- mostat to release static build-up before touching any keys.

If at any time during testing your system does not operate properly, contact a qualified serviceperson.

Fan Operation

If your system does not have a G terminal connection, skip to Heating System.

1.Turn on power to the system.

2.Move FAN switch to ON position. The blower should begin to operate.

3.Move FAN switch to AUTO position. The blower should stop immediately.

Cooling System

!CAUTION

To prevent compressor and/or property damage, if the outdoor temperature is below 50° F, DO NOT operate the cooling system.

This thermostat has a time delay between cooling cycles to allow the head pressure in the compressor to stabilize. If the tempera- ture is adjusted to call for cool within 5 minutes of the last cycle the snowflake icon will blink indicating the thermostat is locked out. After 3 to 5 minutes, the compressor will start and the snowflake icon will stop flashing. This helps prevent the compressor from cycling too quickly and is normal operation for the thermostat.

1.Move SYSTEM switch to COOL position.

2.Press to adjust thermostat setting below room tempera- ture. The blower should come on immediately on high speed, followed by cold air circulation

3.Press to adjust temperature setting above room tem- perature. The cooling system should stop operating.

Heating System

1.Move SYSTEM switch to HEAT position. If the heating system has a standing pilot, be sure to light it.

2.Press to adjust thermostat setting above room tempera- ture. The heating system should begin to operate.

3.Press to adjust temperature setting below room tem- perature. The heating system should stop operating.

700 specifications

The White Rodgers 700 series thermostats are an exemplary fusion of innovation, reliability, and user-friendly design, making them a popular choice for heating and cooling control in residential and commercial environments. Known for their advanced features, these thermostats cater to diverse heating and cooling systems, ensuring optimal temperature management and energy efficiency.

One of the standout features of the White Rodgers 700 series is its digital display, which offers clear visibility of temperature settings and system status. This intuitive interface allows users to easily navigate through various functions, enabling quick adjustments to heating and cooling preferences. The large, backlit display is particularly beneficial for users in low-light conditions, providing visibility without straining the eyes.

The 700 series is equipped with smart technology that enhances its usability. Many models feature programmable settings that allow users to customize their heating and cooling schedules based on their daily routines. This programmability can lead to significant energy savings, as the thermostat can automatically adjust settings during times when the home is unoccupied or when more efficient temperatures are desired.

Moreover, the White Rodgers 700 series incorporates advanced climate control technologies that optimize system performance. Features like adaptive recovery technology ensure that the desired temperature is reached as efficiently as possible without overshooting, thereby maintaining comfort while minimizing energy waste. This technology helps prolong the lifespan of HVAC systems by reducing wear and tear from constant cycling.

Compatibility is another significant advantage of the White Rodgers 700 series. These thermostats can work with a wide range of heating and cooling systems, including conventional, heat pump, and gas systems. This versatility makes them ideal for homeowners looking to upgrade their thermostat without the need for expensive alterations to their existing HVAC infrastructure.

In terms of security, some models within the series offer lockout features, providing peace of mind for users by preventing unauthorized changes to the temperature settings. This is particularly useful in settings where many individuals have access to the thermostat.

Maintenance reminders and filter change alerts are other essential characteristics of the 700 series, encouraging users to perform regular upkeep, which ultimately contributes to the longevity and efficiency of their HVAC systems.

Overall, the White Rodgers 700 series thermostats exemplify modern temperature control technology, combining user-friendly interfaces, smart features, and compatibility with various HVAC systems to deliver a reliable solution for temperature management. With their energy-saving capabilities, these thermostats not only enhance comfort but also support sustainable living through efficient energy usage.
