DESCRIPTION The RC-81 is a precision digital thermostat with Real Time Pricing for single stage heating and cooling systems.
OPERATION To take advantage of all the benefits and features offered by your thermostat, we recommend that you start by becoming familiar with its operation. - 1 : 7 P DAY 6 COOL AUTO 2 3 4 5 Hold Prog Mode Fan OMNISTAT 1 Display The Display is used to show current time, temperature, outdoor temperature (optional), mode, and to give useful information that will guide you through normal operation of your thermostat. 2- Hold Press the Hold key to set the system into Hold mode.
4- Mode Press the Mode key to set the thermostat mode to Off, Heat, Cool, or Auto. In Off mode, the heating and cooling systems are both off and do not respond to changes in temperature settings. In Heat mode, the heating system responds to maintain your desired heating setting. In Cool mode, the cooling system responds to maintain your desired cooling setting. In Auto mode, your thermostat will automatically switch between heat and cool to maintain your desired heating and cooling settings.
DISPLAY The following icons will be displayed during normal operation: 1 2 : 13 HOLD 12 MORN DAY EVE NITE 11 REMOTE A DESIRED 3 OUTSIDE 10 OFF COOL HEAT FAN AUTO 9 8 7 4 5 6 1- Temperature Display Shows the current temperature, desired temperature, or heating and cooling settings. 2- Time Display Shows the current time of day. 3- DESIRED DESIRED is displayed when the temperature display shows the desired temperature setting.
5- The is displayed when the heating or cooling system is running. 6- COOL COOL is displayed when the system is in Cool mode. 7- AUTO AUTO is displayed when in automatic changeover mode. 8- HEAT HEAT is displayed when the system is in Heat mode. 9- FAN FAN is displayed when the fan is set to run continuously. 10- OFF OFF is displayed when the system is in the Off mode. 11- REMOTE REMOTE is displayed when the last command received by the thermostat was sent by a remote system.
FILTER REMINDER Your thermostat logs the amount of time your heating and cooling system has been running and gives you a reminder when it's time to replace your filter. " F I L t " will be displayed every four seconds in the place of the time display when it is time to change you filter. To clear the reminder, press the Prog key. The display will return to normal in 10 seconds.
The thermostat will control using the original setting and the variation for the rate in use. For example, if your heat setting is 68 degrees, the rate is hi, and the variance for hi is set to 3, the thermostat will control to 65 degrees. Real time pricing variations can be used with or without the programming feature of the thermostat. SETTING THE CURRENT TIME AND DAY To set or change the current time and day, press and release the Prog key. The hour will blink. 1.
: P DAY OFF Press the Mode key when complete, or simply wait 8 seconds for the display to return to normal. PROGRAMMING Your thermostat may be programmed to set the variance for higher energy rates and to adjust the heat and cool settings up to 4 times per day (MORN, DAY, EVE, NITE). You can setup a temperature time schedule for weekdays, Saturday, and Sunday. When in programming mode: 1. The item that is being programmed will flash. 2. The up arrow key (∧) is used to increase the value. 3.
VAR RATE 1. Use the arrow keys to change the variance for the MID rate. 2. Press the Prog key to advance to the HI rate. Use the arrow keys to change the variance for the HI rate. 3. Repeat step 2 for the CRIT (critical) rate. (Typical settings for variance are: MID: 1, HI: 3, CRIT: 6) OVERRIDING THE VARIATION SETTINGS To override the real time pricing system, put the thermostat in Hold mode by pressing the Hold key. HOLD is displayed when the system is in Hold mode.
To view or change the programmed time schedules of your thermostat, press the Prog key four times (seven times if real time pricing is in use). The weekday MORN time will flash. 1. Use the arrow keys (∧-∨) to change the scheduled time for the displayed period (MORN, DAY, EVE, or NITE). : MORN A DESIRED 2. Press the Prog key to advance to the next item. 3. Use the arrow keys (∧-∨) to change the desired cool setting. : MORN A DESIRED COOL 4. Press the Prog key to advance to the next item. 5.
Repeat steps 1-6 for the DAY, EVE, and NITE periods. Afterwards, repeat steps 1-6 for 4 daily periods on Saturdays (Day 6), and 4 daily periods on Sundays (Day 7). The temperature display will show "6" for Saturdays, and "7" for Sunday times. SYSTEM MODE Your thermostat can be connected to an automation system or personal computer. With network software, the remote system can send commands to the thermostat to change mode, cool setting, heat setting, status of fan and hold, and other items.
ANTICIPATION Your thermostat has a sophisticated control system designed to keep you comfortable while saving energy. Part of the control system is a feature called "anticipation", which anticipates the need to turn the system on or off before the temperature is actually at the setting. As humans, we perceive temperature as a combination of heat in the air and heat radiated from the walls and surroundings. The thermostat also measures a combination of air and wall temperature.
TIME SCHEDULES The table below shows the time schedules that are currently set into your thermostat. There is a blank table at the bottom that can be used to plan changes to the current schedule.
