The temperature setting cannot be programmed. A temperature drop to below 45 degrees F +/-3 degrees F (7C +/- 2C) at the control panel will result in an alarm and call.

The Reliance THP201 operated off 120V power via a AC/DC wall adapter and a 9B battery to operate during power outages.

A water sensor is housed in a separate plug-in accessory, which is included with Model Number THP201. The water sensor can be placed up to 100 feet from the control panel using additional telephone line.
A single or multiple alarm condition will initiate the phone-out sequence features of this monitoring system. After a 5- or 30-minute delay (depending on the switch setting selected for the “Call Delay Time”) the monitoring system will call the first programmed telephone number and wait up to 10 rings for the called telephone to answer. If the called telephone does not answer, or answers and no response code keys are pressed, the monitoring system will call a second and third telephone number (if programmed), each time allowing 10 rings. The monitoring system will continue the calling sequence at 15-minute intervals until a called phone is answered and a response code is entered, or until an alarm condition no longer exists.
