Operations 17 7271. 70 Different Operation Modes Your thermostat has an additional operational switch which enables you to select 3 different modes of operation for heating. 1. Normal Operation: In this operation your thermostat will function in accordance to your heating and A/C programs. The sequence of operation of different stages will be as per table on page 28. What Is Temperature Recovery? Consider the following example for explanation. Suppose the thermostat is programmed to turn the heat on at 6:00 AM to raise the temperature from a set-back temperature of 60°F to 68°F. In the normal operation mode, the heat will turn on at 6:00 AM and begin to raise the temperature to 68°F. The room will attain 68°F sometime after 6:00 AM, for example 30 minutes later at 6:30 AM. The time to raise the temperature from 60°F to 68°F will depend on several factors like outside temperature, efficiency of the unit and insulation of the house. At about 6:30 AM the temperature in the 2. Emergency Operation: In this operation the compressor will not operate. Only auxiliary heat will control the room temperature as per your heating program. For example, you might select this mode to bypass your heat pump, if you suspect it is not operating properly. 3. Auto Recovery Operation: See next section for detailed explanation. house will be the desired temperature of 68°F. In temperature recovery mode, the heat will turn on sometime before 6:00 AM, so that at 6:00 AM, the program time, the temperature in the house will already have achieved the desired temperature of 68°F. This early turn on time period is called recovery time. The Hunter Energy Monitor has an exclusive method built into the thermostat computer. This method is designed to maximize efficiency of recovery in the most economical way, without the use of auxiliary heat (or minimum use if necessary), which will result in maximum savings in various weather conditions. How Does Temperature Recovery Work? Consider The Following Example. PROGRAM # TIME PROGRAM TEMPERATURE 1 6:00 AM 68°F 2 8:30 AM 60°F 3 4:00 PM 68°F 4 11:00 PM 58°F Present time is 2:00 AM, the effective current program is number 4. The next program is at 6:00 AM at 68°F. In the normal operation, at 6:00 AM, the furnace will turn on to raise the temperature from 58°F. Your house will attain 68°F some time after 6:00 AM. For our understanding, say 6:35 AM. The time required to reach 68°F will depend upon outside temperature on that day and the efficiency of your heating system. In temperature recovery operation, your system will gradually raise the house temperature some time prior to 6:00 AM, o that at 6:00 AM your system will have achieved the programmed temperature. The time to activate temperature recovery and sequence of operation of different stages of the system is set by an internal computer after several complex computations based on how “hard” your system needs to work to maintain the programmed temperature. At 6:00 AM, the recovery cycle stops and automatically controlling the system normally, auto recovery will also take place during program 2, to raise the temperature from 60°F to 68°F just prior to reaching program 3 at 4:00 PM. We recommend using this exclusive feature of auto recovery as often as you can to optimize the efficient use of energy. When temperature recovery is activated, “AUTO RECOVERY” will appear, indicating that recovery has begun. When the set temperature is achieved and the next program time is reached, the recovery cycle ends and the “AUTO RECOVERY” will disappear from the display. NOTE: Auto Recovery will not be activated in manual override modes. Read This First Before Installing Thermostat IMPORTANT 1 1 Read the entire installation section of this Installation Manual thoroughly before you begin to install or operate your thermostat. • Remove the mylar label from the display window. INSTALLATION 2 2 All installation is normally performed at the thermostat. OPERATION 3 3 This Hunter Thermostat is designed to operate with most single and multistage heat pumps having 24V controls. The system will control two stages of compressor and two stages of auxiliary heat. The relay current is limited to 1.0 amps for each stage. COMPRESSOR PROTECTION 4 4 The thermostat provides a 4-minute delay after shutting off the compressor before it can be restarted. This feature will prevent damage to the air conditioner compressor caused by rapid cycling. It does not provide a delay when there are power outages. TEMPERATURE RANGE 5 5 This thermostat can be programmed between 40°F and 90°F. However, it will display room temperatures from 32°F to 99°F. POWER FAILURE 6 6 The thermostat is fully battery operated and does not require power from the control circuit. Whenever the main power is interrupted or fails, the battery power retains the programs and current time. BATTERY WARNING 7 7 When the batteries are low, “LOW BATT” indicator on the display will flash. When this happens, install new batteri...
