(Remotech) Installing The ZTS-100 Thermostat

Last Updated: May 10, 2013 02:11PM PDT

Please read these instructions carefully before installing your new ZTS-100 thermostat! 

Pay close attention to all warnings and notes and carefully follow the installation steps in the order they are presented, which will save time and minimize the risk of damaging the thermostat or the system it controls.

First, turn off the electric source to your system from your circuit breaker before installation!

WHERE TO INSTALL:

The thermostat is restricted to indoor use only. For most accurate results, it should be mounted on an 
inner wall about 5-6 feet above the floor at a position where it is readily affected by changes of the general room temperature with freely circulating air. Avoid mounting the thermostat above or near hot surfaces or equipment such as a heater, refrigerator or TV. Avoid mounting where it will be exposed to direct sunshine, drafts, or in a laundry room or other enclosed space. Do not expose this thermostat to dripping or splashing.

WIRING:

- Be sure the operation mode is OFF and Fan selection is Fan Auto

- Wire the proper cables at the terminal block according to the circuit diagram

- Afterward, push all cables back into the wall

- Do not use metal conduit or of cable provided with a metal sheath

- It's recommended that you have a fuse or protective device in the line circuit

Important!

The ZTS-100 can be powered by alkaline batteries AA x 4pcs or 24Vac. Connect the "24Vac Common" (typically the black wire/terminal) and "24Vac Power" (typically the Red wire/terminal) from the HVAC system to the ZTS-100 HVAC System terminal block "C" and "RH" or "RC" terminals (the RH and RC terminals are default tied together).

For Common or Split Transformer Systems:

Most HVAC systems have a common heating and cooling transformer. A wire is connected to tie the RH and RC inputs together for this configuration. If you have a system with separate heating and cooling transformers, you will need to disconnect the RH and RC wire.

When wiring split systems, wire the heating systems "24Vac Power" (red wire) to the ZTS-100 "RH" terminal, and wire the cooling systems "24Vac Power" to the ZTS-100 "RC" terminal. Also wire the cooling system's "24Vac Common" to the ZTS-100 "C" terminals.

NOTE:  Do not split RC/RH for heat pump systems!

There are also a series of small jumper connections on the terminals of your ZTS-100 thermostat.  Depending on your type of home climate system, please be sure the jumpers are in the placements described below:

1 -  If your home HVAC system is electric powered and you don't have a heat pump (Default)

2 - If your home HVAC is electric powered and does have a heat pump

3 - If your home HVAC is gas powered and you don't have a heat pump (Default)

4. If your home HVAC is gas powered and does have a heat pump


MOUNTING THE THERMOSTAT

1. Open the ZTS-100 by pushing the hook (Figure 5 below)

2. Install four AA batteries (Alkaline batteries are recommended)

3. Check the polarity of the batteries and the "+/-" marks inside the battery compartment

4. Connect 24Vac power if using 24Vac power source

5. Place the cables at the hole near the terminal block

6. Insert 2 pieces of wall anchors into the holes of the wall

7. Fasten the thermostat with 2 pieces of long screws through the 2 mounting holes (Figure 6 below)

8. Install the top housing by hooking the bottom (Figure 6 below)



When you've connected everything, mounted the thermostat and snapped the cover back into place, you can turn on the electricity to your HVAC system again and proceed to pairing the thermostat to your Smart Controller.
