Installation Instructions

Remove and Replace the old thermostat

To install the thermostat properly, please follow these step by step instructions. If you are unsure about any of these steps, call a qualiﬁed technician for assistance.

• Assemble tools: Flat blade screwdriver, wire cutters and wire

strippers.

• Make sure your Heater/Air Conditioner is working properly

before beginning installation of the thermostat.

• Carefully unpack the thermostat. Save the screws, any brackets,

and instructions.

• Turn off the power to the Heating/Air Conditioning system at

the main fuse panel. Most residential systems have a separate breaker for disconnecting power to the furnace.

• Remove the cover of the old thermostat. If it does not come off

easily, check for screws.

• Loosen the screws holding the thermostat base or subbase to

the wall and lift away.

• Disconnect the wires from the old thermostat. Tape the ends of

the wires as you disconnect them, and mark them with the letter of the terminal for easy reconnection to the new thermostat.

• Keep the old thermostat for reference purposes, until your new

thermostat is functioning properly.

Installation Instructions

Before you go any further, determine what your existing wiring and equipment situation is.

A. If you have a Heating only system without Air Conditioning, the First

Aler t model sTHERM-50 0 will re quire 3 wires: R (24Vac) , C (24Vac ) and W (H eat). Mos t systems that only have Hea ting us e very simple thermostats that require 2 wires: the R (24Vac ) and W ( Heat). The THERM -500 thermostat re quire s 3 wires to supply power to the thermostat. In this case an Add-a-W ire ac cessory will not work and it will be necessar y to ins tall another wire for the C (24Vac) connection.

B. If you have a single stage fossil fuel heater with air c ondi tioning, the

First Aler t model THERM-5 00 will require 5 wires for indep endent fan control. They are R (24Vac), C (24Vac), W (H eat), Y (Cooling ), and G (Fan ). You may connec t only 4 wires, a s instructed in the “Making 4 Wires Work When 5 Wire s Are Required” sec tion on p age 50 .

If there are only 4 wires present that ar e connecte d to the existin g

thermostat, there are at least 3 options available to connect the First Alert THERM-500:

1. Us e the 4 wires as instru cted in the“Making 4 Wires Work When 5 Wires Are Required” section on page 50, and note that the fan w ill only opera te with a Heating or Cooling demand.

2. Pull new thermostat wire from the HVAC equipment to the thermostat so tha t there are at least 5 wires available.

3. Pur chas e and ins tall an Add-A-Wire accessory.

C. If you have a multi-stage HVAC sys tem compri sed of a fossil fuel

heater with air conditioning, the First Aler t model THERM-5 00 will require the 5 wires mentione d above ( R, C, W, Y, G) plus an additional wire for each additional stage of Heating or Cooling. You may reduce the 5 wire requirement to 4 if you give up independent fan control following the instruction in the “Making 4 Wires Work When 5 Wires Are Required” section on page 50, or use the optional Add-A-W ire ac ce ss or y.

Installation Instructions

D. If you have a heat pum p with out aux heat, the First Alert model

THERM -500 will require 5 wires: R (24Vac), C (24Vac), W1/ O/ B (Reversing Value) , Y (1st Stage Compr essor), and G (Fan).

If you are short 1 wire, there are at least 3 options available to connect

the First Alert mo del TH ERM- 500:

1. Us e the available w ires as instructed in the“Making 4 Wires Work When 5 Wire s Are Re quired” sec tion on p age 50 and note that the fan will only operate with a He ating or Cooling demand.

2. Pull new thermostat wire from the HVAC equipment to the thermostat so tha t there are at least 5 wires available.

3. Pur chas e and ins tall an Add-A-Wire accessory.

E. If you have a heat pump with aux heat, the Fir st Alert model

THERM -500 will require 6 wires: R (24Vac), C (24Vac), W1/ O/ B (Reversing Value) , Y (1 (Fan ).

If you are short 1 wire, there are at least 3 options available to connect

the First Alert mo del TH ERM- 500:

1. Us e the available w ires as instructed in the“Making 5 Wires Work When 6 Wire s Are Re quired” sec tion on p age 51 and note that the fan will only operate with a He ating or Cooling demand.

Installation Instructions

Making 4 Wires Work When 5 Wires Are Required

If you have System B from page 48 and you would like to install the Fir st Aler t model THERM-5 00 using only 4 wires, follow the dire ctions below. You will need a screwdriver along with a 3" long piece of thermostat wire to use as a jumper :

1. Make sure the power is of f.

2. L abel and disconne ct wires at the thermost at. Please note the color and corresp onding wire de signator with each color. For example: The R wire is red and the W wire is white and so on. You will need this inf ormation handy for the next step at the HVAC equipment.

3. At the HVAC equipment end of the thermostat wires (usually at the furna ce) , locate the terminals that the wire s are at tached to.

4. Remove the “G wire” from the terminal marked G.

5. Place the “G wire” on terminal C.

6. Place one end of the 3" long jumpe r on terminal G.

7. Place the other end of the 3 " long jumper on terminal Y. Please note that there will be more than 1 wire on terminal Y.

8. W hen connec ting the wires to the Fir st Alert thermostat, note that the wire that was previously conne cted to the G ter minal of the old thermostat will now be required to be connected to the C terminal on the Fir st Alert thermo stat. All other wires will be connec ted such that the conne ctions on each end of the indivi dual w ires match

terminal designations. For example : Conne ct the yellow wire on the thermostat end to the Y terminal on the thermostat. The yellow wire will be connected to the Y terminal on the HVAC equipment end also.

Making 5 Wires Work When 6 Wires Are Required

If you have System C or E from page s 48-49 or any system that requires 6 wires, and you would like to install the First Alert model T HERM -50 0 using only 5 wires, follow the direc tions below. You will need a s crewdriver along with a 3" long pie ce of thermostat w ire to us e as a jump er:

1. Make sure the power is of f.

3. At the HVAC equipment end of the thermostat wires (usually at the furna ce) , locate the terminals that the wire s are at tached to.

4. Remove the “G wire” from the terminal marked G.

5. Place the “G wire” on terminal C.

6. Place one end of the 3" long jumpe r on terminal G.

to be set for GAS/EL. Consult the commercial heat pump literature.

When the GAS/EL or HP dip switch is conﬁgured for HP, this dip switch (O or B) must be set to control the appropriate reversing valve. If O is chosen, the W1/O/B terminal will energize in cooling. If B is chosen, the

W1/O/B terminal will energize in heating.

1. When GAS/EL or HP is set for GAS/EL: This switch (GAS or ELEC) controls how the thermostat will control the Fan (G) terminal in heating mode. When GAS is chosen, the thermostat will not energize the Fan (G) terminal in heating. When ELEC is chosen the thermostat will energize the fan in heating.

Troubleshooting

• SYMPTOM: The thermostat touchscreen buttons are not responsive. CAUSE: The touchscreen is out of calibration. REMEDY: Remove the thermostat from the backplate. Push the

thermostat back onto the backplate, while keeping your ﬁnger pressed ﬁrmly against the center of the touchscreen, until the Calibration screen appears. Re-calibrate the Touchscreen. See Touch Calibration section of

full user’s manual (page 19).

• SYMPTOM: The display is blank. CAUSE: Lack of proper power. REMEDY: Make sure the power is on to the HVAC and that you have

24vac between R & C.

• SYMPTOM: The air conditioning does not attempt to turn on.

CAUSE: The cooling setpoint is set too high. REMEDY: Lower the cooling setpoint or lower the cooling set-point

limit. See Setpoint Limits (page 28).

• SYMPTOM: The heating does not attempt to turn on.

CAUSE: The heating setpoint is set too low. REMEDY: Raise the heating setpoint or raise the heating set-point limit.

See Setpoint Limits (page 28).

• SYMPTOM: When controlling a residential heat pump, and asking for cooling, the heat comes on.

CAUSE: The thermostat reversing valve dip switch is set for “B”. REMEDY: Set the reversing valve jumper for “ O ”.

• SYMPTOM: When calling for cooling, both the heat and cool come on. CAUSE: The thermostat equipment dip switch is conﬁgured for “HP”

and the HVAC unit is a Gas/Electric. REMEDY: Set the equipment dip switch for “Gas”.

• SYMPTOM: Air handler control board fuse blows when thermostat is attached to backplate with power on, but does not blow until the thermostat is placed onto the backplate.

CAUSE: The Outdoor sensor and/or sensor wiring is shorted. REMEDY: Check/replace Outdoor sensor and/or sensor wiring.
