Frequently Asked Questions - CL-100 Irritrol
How do I install the Irritrol CL-100 thermostat?
Turn off power to your HVAC system at the breaker. Remove the old thermostat and label wires according to the existing terminals. Mount the CL-100 base to the wall, connect wires to the corresponding terminals (e.g., R, W, Y, G), attach the faceplate, and restore power. Refer to the manual for wire identification.
How do I set the time and day on the CL-100?
Press the SET button until the time display flashes. Use the up/down arrows to adjust hours and minutes, then press SET again for day. Repeat until all settings are saved. The thermostat uses a 12-hour clock.
How do I program a heating schedule?
Press PROG to enter scheduling mode. Select the day (or group of days) and period (Morning, Day, Evening, Night). Adjust the desired temperature and start time using arrows. Press PROG to save each period. Repeat for all periods and days.
What does the 'Filter' indicator mean and how do I reset it?
The filter icon reminds you to replace or clean your HVAC filter after a set number of operating hours (default 500 hours). To reset, press and hold the FILTER button for 3 seconds until the icon disappears. Regular filter changes maintain efficiency.
Why is my CL-100 display blank or not working?
Check if the thermostat is receiving power. If battery-powered, replace the two AA alkaline batteries. If wired, ensure the C-wire (common) is connected and the breaker is on. A blank display usually indicates no power.
Can I use the CL-100 with a heat pump?
Yes, the CL-100 supports single-stage heat pumps. Set the system type switch on the back to 'HP' (heat pump) instead of 'CONV' (conventional). Ensure wiring matches: O/B terminal for reversing valve.
How do I lock the thermostat to prevent unauthorized changes?
Press and hold the UP and DOWN arrows simultaneously for 5 seconds. A lock icon will appear. To unlock, repeat the same gesture. This prevents temperature adjustments without the key combination.
What temperature range does the CL-100 support?
The thermostat can control temperatures between 40°F and 99°F (4°C to 37°C) for heating and 60°F to 99°F (16°C to 37°C) for cooling. Set points beyond these ranges will be ignored.
How do I clean the CL-100 thermostat?
Use a soft, dry cloth to gently wipe the display and housing. Do not use liquids, sprays, or abrasive cleaners. Ensure the device is powered off before cleaning. Avoid moisture entering the vents.
Where can I find replacement parts for my CL-100?
Contact Irritrol customer support or visit their official website. Common replaceable parts include the battery cover and mounting screws. The thermostat itself is not user-serviceable beyond battery replacement.
