INSTALLATION PROCESS
1. Remove the Z8 front cover by placing two fingers into indents along both sides of the controller.
Front cover should pull away from back panel with a small amount of upward force. This will expose
the terminal blocks, mounting holes, and wireless module.
2. Place the Z8 back plate on a flat surface for mounting. Mark mounting holes and drill 3/16” holes into
mounting surface (Refernce Page 12 Figure 7). Note the provided wiring channels. There is also a
channel for the static pressure tubing.
3. If the Z8 is installed inside the HVAC unit or is enclosed in metal. The wireless module will need to be
removed from the Z8 and installed either below the roof-line or outside the HVAC unit on a plastic
weatherproof electrical box (Reference Pages 13 and 14 Figures 8 and 9). The Z8 Wiring Guides are layed
out as follows:
a. Fig. 8 shows wiring the Wireless Module to the Z8. (Page 13)
b. Fig. 9 shows installing the Wireless Module on a plastic weatherproof electrical box. (Page 14)
c. Fig. 10 shows the Z8 wired to a Conventional HVAC unit. (Page 15)
d. Fig. 11 shows the Z8 wired to a Conventional HVAC unit with a Bypass. (Page 16)
e. Fig. 12 shows the Z8 wired to a Conventional HVAC unit with a Bypass and Economizer. (Page 17)
f. Fig. 13 shows the Z8 wired to a Conventional HVAC unit with a VFD. (Page 18)
g. Fig. 14 shows the Z8 wired to a Conventional HVAC unit with a VFD and Economizer. (Page 19)
h. Fig. 15 shows the Z8 wired to a Conventional HVAC unit with an Economizer. (Page 20)
