Honeywell RLV450 Manual: Questions and Answers
What's the difference between 15-second and 15-minute cycle settings on the Honeywell RLV450?
15-second cycles provide better temperature control. Select 15-minute cycles only if you have a fan-forced heater. User Guide, p. 2
What does the LP indicator on the Honeywell RLV450 display mean?
LP signals the thermostat has no power. It appears for two minutes during a power outage or when the heater's thermal protection opens. User Guide, p. 1
What does it mean when the FAN word appears on the Honeywell RLV450 display?
FAN indicates that 15-minute cycle mode is selected, which is required for fan-forced heaters. User Guide, p. 2
