The installation of thermostats, touch screen 7-day programmable Honeywell RTH8500D on a standard 24-volt heating and cooling is not complicated, or if the instructions are followed exactly. Although this article will explain how it's done I could not enough that you have provided the operating instructions for the Honeywell RTH8500D before you start reading to highlight the installation.
Before you start gathering the necessary tools: a hammer, pencils, 3 triples'A' alkaline batteries, 2 screwdriver, Phillips number, a regular screwdriver, wire, adhesive tabs (should be included with the RTH8500D Honeywell), a power drill and appropriate bit (3 / 16 inch for drywall and 7 / 32-inch cleaning).
Now you are ready to begin. First, the turn the power switch on the HVAC and then remove the old thermostat from the wall plate. Do not remove the cables. It 'important to remember not to the colors of the wires, but the oldThermostat correctly identify the wires.
The first thing to check is the C and C1 or wires. If there are 2 C or C1 are then attach wires to RTH8500D Honeywell. Instead of wire to wrap the bare wires. If there is one thread C or C1, then highlight the old thermostat to a sticky label this wire as C. If there are still cover the unused cable ends of electrical conductors. These wires are not used for installation.
Now you can use a cableat a time and follow the old terminal on the thermostat for the identity of each cable. Once the wire is then identified a sticker on the wire, so do not forget where it should go. Then disconnect the old thermostat and wrap the cable around a pencil to stop falling back into the slot of the wall.
Here is a guide for wire marking:
RC RC or R
R, RH, 4, or V to R
W, W 1 or W to H
Y, Y1 or M to Y
G or F to G
C, C1, X or B to C
Y2 Y2
W2W2
Once all the cables properly labeled separately and then unscrew the plate and take the old wall Honeywell RTH8500D wall plate and thread the wires through the middle. Then take a pencil and mark the holes. Next, take the wall plate and holes with the right (3 / 16 inch for inch drywall and 7 / 32 for cleaning).
Once done, put the pins in two holes and tap with a hammer. Then run the cable through the new wall plate and screwthe wall plate to the wall. You can then connect the wires to the terminals marked on the appropriate RTH8500D Honeywell.
It is now almost finished. Insert the 3 triple 'A' alkaline batteries in the thermostat Honeywell programmable RTH8500D and you will find a tab at the bottom left, "remove during installation," he says. Remove the card and press the thermostat on the wall plate, the thermostat clicks.
Finally, on again and set the HVACCalendar, clock, and the guy with the big touch-screen interface, and you are ready to begin, in the program settings for each day of the week.
If you have problems in the user and then call the emergency service Honeywell.
