Installation Location; Wiring - Remotec ZTS-100 User Manual

Installation Location:

The Thermostat is restricted to be used in indoor only. It should be mounted on an
inner wall about 1.5m 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.

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
- Recommends adding 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).
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.
