12	Critical. (Thermostat) The thermostat cannot find an Comfort Sync­enabled indoor unit. Thermostat did not find an Indoor Unit. Make sure there is an Comfort Sync indoor unit on the system. Check R, i+, i­ and C connections, ohm wires and cycle power. Replace indoor unit control board if there is no response.
14	Critical. (Thermostat) The thermostat found more than one thermostat, more than one indoor unit, or more than one outdoor unit on the system. Check wiring and remove duplicate equipment. Reconfigure system.
18	Minor. (Thermostat) The outside temperature is below the level where the heat pump is programmed to heat the home. The system will not use the heat pump to warm your home. Notification only ­ Outdoor Temp is below the Low Balance Point. Heat Pump will not be used to service a heating demand.
19	Minor. (Thermostat) The outside temperature is higher than the level where the furnace or electric heat is programmed to work. The system will only use the heat pump to warm your home. Notification only ­ Outdoor Temp is above the High Balance Point. Indoor Unit (furnace or air­handler) will not be used to service a heating demand.
29	Critical. (Thermostat) The thermostat is reading an indoor temperature that is higher than 99ºF. The thermostat will not allow any heating operation to begin until it senses a temperature lower than 99ºF. Indoor temperature rose above 99ºF during a heating or cooling demand. Heating operation is not allowed. Check to ensure that Heating Equipment is not stuck ON (reversing valve, etc.). Check the accuracy of the thermostat temperature sensor. Select cooling system mode to cool the indoor space.
30	Moderate. (Thermostat) The thermostat is reading an indoor temperature that is lower than 40ºF. The thermostat will not allow any cooling operation to begin until it senses a temperature higher than 40ºF. Indoor Temp fell below 40ºF. Cooling operation is not allowed. Check to ensure that cooling equipment is not stuck ON. Check accuracy of the thermostat temperature sensor. Select heating system mode to heat the indoor space to above 40ºF.
31	Critical. (Thermostat) The thermostat has lost communication with the (furnace, air­handler or outdoor unit) for more than 3 minutes. [Indicated unit] has not communicated with thermostat for more than 3 minutes. Check connections. Ohm wires. If fault persists, then cycle power. Fault clears after communication is restored.
32	Moderate. (Thermostat) The (furnace, air­handler or outdoor unit) is resetting itself. [Indicated unit] is resetting itself. This event may occur during a power outage or power fluctuation in the system. If persistent or if it coincides with the system operation then proceed with the following steps. Check the power connections, check the amp draw at the transformer (the transformer maybe overloaded) and check 24VAC voltage at the DEVICE. The alarm is only cleared by pressing the clear button on the Installer Alerts Tab. If the fault persists after checking the connections, replace the unit's control board.
34	Critical. (Thermostat) The thermostat does not know the capacity (tonnage) of the (furnace, air­handler or outdoor unit).

105	Critical. (Thermostat / Furnace / Air Handler / Outdoor Unit) The (Thermostat, furnace, air­handler or outdoor unit) has lost communication with the rest of the system. Equipment is unable to communicate. This may indicate the existence of other alarms/ codes. In most cases errors are related to electrical noise. Make sure high voltage power is separated from RSBus. Check for incorrectly wired and/or loose connections between the Thermostat, indoor unit and outdoor unit. Check for a high voltage source of noise close to the system. Generally, this is a self­recoverable error.
110	Critical. (Furnace) The line voltage is too low. This alarm/code may appear during a brownout. Line voltage is below its designed operating value. Check and correct the power line voltage.
111	Critical. (Furnace) The line power voltage wiring is reversed. The unit is reporting that its power line and neutral are reversed. Turn off the power to the system and correct the line power voltage wiring. System resumes normal operation 5 seconds after fault recovered.
112	Critical. (Furnace) The reporting device cannot find earth ground. The thermostat will shut down the system. Provide proper earth ground to the equipment. System resumes normal operation 5 seconds after fault recovered.
113	Critical. (Furnace) The line voltage is too high. Line voltage high (voltage higher than nameplate rating). Provide power voltage within proper range. System resumes normal operation 5 seconds after fault recovered.
114	Critical. (Furnace / Air Handler) There is a frequency/distortion problem with the power to the (furnace or air­handler). This alarm/code may indicate transformer overloading. Check the voltage and line power frequency. Check the generator operating frequency, if the system is running on back­up power. Correct voltage and frequency problems. System resumes normal operation 5 seconds after fault recovered.
115	Critical. (Furnace / Air Handler) The 24VAC to the (furnace or air­handler control board) is lower than the required range of 18 to 30VAC. 24­Volt Power Low (Range is 18 to 30 volts). Check and correct voltage. Check for additional power­robbing equipment connected to system. This alarm/code may require the installation of an additional or larger VA transformer.
117	Minor. (Furnace) The reporting unit has poor earth grounding. Provide proper grounding for the unit. Check for proper earth ground to the system. The alarm/code will clear 30 seconds after it is corrected.
120	Moderate. (Thermostat / Furnace / Air Handler / Outdoor Unit) There is a delay in the (Thermostat, furnace, air­handler or outdoor unit) responding to the system. Typically, this alarm/code does not cause any issues and will clear on its own. The alarm/ code is usually caused by a delay in the outdoor unit responding to the thermostat. Check all wiring connections. Cleared after unresponsive device responds to any inquiry.
124	Critical. (Thermostat / Furnace / Air Handler / Outdoor Unit) The thermostat has lost communication with the (furnace, air­handler or outdoor unit) for more than 3 minutes. Equipment lost communication with the thermostat. Check the wiring connections, ohm wires and cycle power. The alarm stops all associated HVAC operations and waits for a heartbeat message from the unit that's not communicating. The alarm/fault clears after communication is re­established.
125	Critical. (Thermostat / Furnace / Outdoor Unit) There is a hardware problem on either the (Thermostat, furnace control board, air­handler control board or outdoor unit control board). There is a control hardware problem. Replace the control if the problem prevents operation and is persistent. The alarm/fault is cleared 300 seconds after the fault recovers.
126	Critical. (Furnace / Outdoor Unit) There is an internal communication problem with the (furnace control board, air­handler control board or outdoor unit control board). There is an internal hardware problem on the control. Typically the control will re­set itself. Replace the control if the problem prevents operation and is persistent. The alarm/fault is cleared 300 seconds after the fault recovers.
130	Moderate. (Air Handler) An air­handler configuration jumper is missing. Configuration jumper(s) missing on control (applicable in non­communicating applications only). Replace the jumper or put wire between terminals on control. Cleared after jumper is connected.
131	Critical. The (Thermostat, furnace, air­handler or outdoor unit) control parameters are corrupted. Reconfigure the system. Replace the control if heating or cooling is not available.
132	Critical. (Air Handler) The device's control software is corrupted. Recycle power. If failure re­occurs, replace the control. System reset is required to recover.

Troubleshooting Wi-Fi

Router / Modem Check If Connection Fails

1. Make sure the router and modem are turned on.

2. Check for connections to other wireless devices and internet connection.

3. Make sure the Comfort Sync thermostat’s Wi-Fi is enabled and connected to the home network (AP).

4. If having difficulty connecting to the router, online research the router model number and/or internet provider to discover and verify that the router band is set to B, G or N bands. You will need to access the routers utility program to make any changes. If not accessible please contact your service provider for help. The thermostat will connect to B, G or N band routers at this time. NOTE: When set to B or G bands, video streaming will likely be slower that N band. If homeowner has implemented a dedicated N band router for the purpose of video streaming, a separate router for the thermostat may be required.

5. Reboot your router.

6. Power cycle the thermostat.

7. Keep cordless phones, microwaves and other electrical equipment at least 3.5 feet (1m) away from access point.

8. Try changing channels on the access point and test it out with one of your internet devices (i.e. laptop, desktop). The IP address to the server from the thermostat will be close to the same IP address from the computer to the server.

Communication Error Screen

Figure 1. Communication Error Screen

During initial thermostat start-up if the following screen appears (see figure 1), this will indicate that the thermostat has been incorrectly wired or has shorted wires. Turn power off to the system and verify that all wiring is correct.
