Installation Guide for the RTH230B Thermostat
The RTH230B installation involves removing the old thermostat, installing the new baseplate, connecting wires, setting the J2 jumper, and inserting batteries. Ensure proper placement for accurate operation.
3.1 Removing the Old Thermostat
To remove the old thermostat, first, ensure the power to the heating system is turned off at the circuit breaker. Remove the batteries from the old thermostat if it uses them. Gently unscrew and pull the thermostat away from the wall. Carefully disconnect the wires from the old thermostat, noting their colors and positions for future reference. Avoid damaging the wires or the wall during removal.
3.2 Installing the New Baseplate
Mount the new baseplate on the wall, ensuring it is level and secure. Choose a location about 5 feet above the floor, avoiding drafts or direct sunlight. Align the baseplate with the wall studs if possible. Use the provided screws to fasten it firmly. If the wall is hollow, consider using wall anchors for added stability. Ensure the baseplate is properly aligned and level before securing it in place. Refer to the manual for specific installation requirements;
3.3 Connecting the Thermostat Wires
Connect the wires to the new baseplate terminals, matching each wire to its corresponding label (e.g., Rh, Rc, W, Y, G). Ensure the red jumper wire is removed in 2- or 5-wire installations. For 3- or 4-wire setups, use the jumper if the fan mode selector is needed. Secure the wires firmly and double-check connections before restoring power to avoid electrical issues.
3.4 Setting the J2 Jumper
The J2 jumper determines fan operation in automatic mode. Remove the jumper for 2- or 5-wire installations or systems without a fan connection. Keep the jumper intact for 3- or 4-wire setups if using the fan mode selector. Properly setting the J2 jumper ensures correct fan control, preventing unintended operation during heating or cooling cycles and maintaining system efficiency.
3.5 Installing the Batteries
Install two AA batteries in the thermostat. Ensure the system is turned off before replacing batteries to prevent the heating/cooling unit from running unintentionally. After installation, the thermostat performs a self-test, displaying the actual temperature. The default setpoint is 70°F (21°C). Replace batteries when the low-battery icon appears, which flashes for 120 days before the thermostat stops controlling the system. Reinstalling batteries restores basic functionality, requiring time and day readjustment, while temperature settings are retained.
Programming and Operating the RTH230B Thermostat
The RTH230B offers programmable modes, allowing users to customize daily schedules with up to four temperature periods. Temporary bypass and energy-saving features help minimize energy consumption.
4.1 Setting Up Daily Schedules
To set up daily schedules on the Honeywell Home RTH230B, begin by ensuring the thermostat’s clock is accurate. Navigate to the programming menu using the ‘Menu’ button and select ‘Schedule’ or ‘Program Schedule.’ Choose between a 5-day (Monday to Friday) or 7-day schedule. For each day, set up to four temperature periods by specifying the start time and desired temperature using the up and down arrows. Select ‘Save’ to store your settings. The ‘Early Start’ feature can be enabled to reach the set temperature by the scheduled time. Temporary bypass allows overriding the schedule temporarily without altering the programmed settings. After programming, the thermostat will automatically adjust temperatures according to your schedule, enhancing comfort and energy efficiency.
4.2 Understanding System Operating Modes
The Honeywell Home RTH230B operates in Heat, Cool, or Off modes. Heat mode activates the heating system, while Cool mode engages the cooling system. Off mode disables both, stopping all heating or cooling activity. The fan can be set to Auto, running only when heating or cooling is needed, or On, operating continuously for enhanced air circulation. These modes allow users to customize their comfort settings efficiently.
4.3 Temporary Bypass Function
The Temporary Bypass Function allows users to override the programmed schedule. When activated, the thermostat maintains a manually set temperature for 2 hours before reverting to the pre-set schedule. This feature is ideal for temporary adjustments without altering the overall program. The house icon flashes during bypass mode, ensuring users are aware of the override period. This function provides flexibility while preserving energy-saving settings.
