Physical Installation and Wiring
CAUTION
- We highly recommend that this installation procedure is performed by a
trained HVAC technician.
- Read the enclosed instructions carefully before installing your new Z-
Thermostat. Pay close attention to all warnings and notes and carefully
follow the installation steps in the order they are presented to save time and
minimize the risk of damaging the thermostat or the system it controls.
- Turn off ZTS-110 and the electronic devices (e.g. heater, cooler) which will
be connected and the electric source before installation and maintenance.
Battery safety!
- Use new batteries of the recommended type and size only.
- Never mix used and new batteries together.
- To avoid chemical leaks, remove batteries from the ZTS-110 if you do not
intend to use the unit for an extended period of time.
- Dispose of used batteries properly; do not burn or bury them.
Read following scenarios carefully before you start as it matters to the
battery life under Z-Wave operation:
ZTS-110 can be powered by 4 x AA batteries, and/or 24Vac C wire.
a) If it is powered by batteries or powered by batteries first then applied with 24Vac
before Z-Wave inclusion, ZTS-110 will self-configure to FLiRS mode which will
save battery life by sleeping.
b) If it is powered by 24Vac or powered by 24Vac first then applied with batteries
before Z-Wave inclusion, ZTS-110 will self-configure to Always Listening Mode
which will not sleep.
c) After inclusion process, ZTS-110 will not detect power source and not allow
changing operation mode. You must perform exclusion process first if need to
change Z-Wave operation mode.
d) After Z-Wave inclusion process, if you reset ZTS-110 to default while both 24Vac
and batteries are applied, ZTS-110 will take 24Vac as primary power source and
self-configure to Always Listening Mode, because reset to default process will
automatically exclude ZTS-110 from the Z-Wave network. You should disconnect
the power source and re-apply the power so ZTS-110 can detect the power
source type and self-configure to corresponding mode.
You may check Glossary for the definition of FLiRS mode and Always Listening
Mode.

Installation Location
The Thermostat is restricted to be used in indoor only. It should be mounted on an
inner wall about 1.5m (5ft) above the floor at a position where it is readily affected
by changes of the general room temperature with freely circulating air. Avoid
mounting above or near hot surfaces or equipment (e.g. TV, heater, refrigerator).
Avoid mounting where it will be exposed to direct sunshine, drafts, or in a laundry
room or other enclosed space. Do not expose this unit to dripping or splashing
liquids.
Physically Installing the Thermostat
1. Open the ZTS-110 by pulling the two sections apart (Figure 2). Use the fingertips
of one hand to grip the tab on the front housing.
2. Apply power to the thermostat:
a) For battery power, install four AA batteries (alkaline recommended). Match
the polarity of the batteries with the +/- marks inside the battery compartment.
b) For 24Vac power, connect the wires as described in "Wiring"
3. Insert the two included wall anchors into the wall, aligned with two of the
mounting holes in the back housing of the thermostat.
4. Fasten the back housing to the wall using the two included mounting screws.
Insert the screws through the mounting holes in the housing and into the wall
anchors. (Figure 3)
5. Align the front housing of the thermostat with the back housing and push until the
housing sections are locked together.
