  • Page 19: Determine The Mounting Location

    Determine the Mounting Location Install the thermostat away from direct sunlight, drafts, doorways, skylights, and windows. Also, make sure that the thermostat is conveniently located for control access and setup. Follow the mounting requirements below: Mount 60 in. (~1.6 m) above the finished floor; this is an HVAC industry standard. On each side of the thermostat, allow at least 12 Xin.

  • Page 20: Mounting

    Mounting Mount the thermostat to an electrical box, low-voltage mounting bracket, or to drywall. Electrical box mounting is preferred to isolate the thermostat from pressure or temperature differentials within the wall. NOTE: For drywall installations, use the included drywall anchors. Make sure to use the outer screw holes on the back plate.
  • Page 21 4. Keep retracing the outline cutting deeper until penetrating the back paper of the drywall. Clear away the excess drywall. NOTE: Identify the wall type as Insulated (packed with insulation) or Non-Insulated (hollow). Assigning the wall type is necessary for Installer Settings configuration. 5.

  • Page 22: Mount To Drywall

    Mount to Drywall For retrofit applications replacing an existing thermostat, turn the HVAC system power off and take a picture or label the current wire configuration before dismantling the current thermostat. NOTES: When replacing a thermostat that was mounted to drywall with anchors, it is recommended to perform one of the following: Mount the HZ-THSTAT 1 in.
  • Page 23 4. Mark the anchor locations. 5. Use a utility knife to cut around the outline of the drawn template. 6. Keep retracing the outline cutting deeper until penetrating the back paper of the drywall. Clear away the excess drywall. NOTE: Identify the wall type as Insulated (packed with insulation) or Non-Insulated (hollow). Assigning the wall type is necessary for Installer Settings configuration.

  • Page 24: System Connections

    System Connections Use the connections on the backplate to wire the thermostat to the HVAC system. Connection Description (1) Common from HVAC system 24VAC transformer. Used to power the device. (1) Reference for heat calls (W/W2) when using two separate reference connections.
  • Page 25 CHVI-RTS-1G-SM-W), remote slab sensor (CHV-RSS), remote temperature and humidity sensors (CHV-RTHS), and 10k thermistors (all sensors and thermistors are sold separately); Connect up to (2) Crestron temperature sensors, (1) Crestron temperature/humidity sensor, or (1) 10k thermistor; Can be designated as an autochangeover sensor for an FCU 2-pipe heat/cool system NOTE: TS1+ and TS1- connections are non-polarized.
  • Page 26 CAUTION: To avoid a possible short circuit, ensure excess wire is pushed back through the hole in the backplate. NOTES: This device is rated for 24VAC operation. For installations without a common wire, the HZA-CONV-THSTAT-2WIRE 2-wire power adapter (sold separately) may be used. For details, refer to Wiring Diagrams on page A miniature flathead screwdriver (not supplied) may be required to attach thinner gauged wires to the backplate terminals.

  • Page 27: R Connections Switch

    R CONNECTIONS Switch The thermostat pulls power from both R terminals and the C terminal. The position of the R Connections switch decides which R connection is routed to the heat calls (W/W2). NOTES: When using the HZA-CONV-THSTAT-2WIRE, always make connections to the R/RC terminals and set the switch to R/RC ONLY.

The unit begins to run in its first stage, and operates at a fraction of its heating capacity.

    Radiant Floor Heating Definitions Radiant floor heating works from the ground up. The heating components are installed below the floor or are embedded in a concrete slab. Heat radiates from the floor to warm the space above. Floor Warming: Operates the radiant floor heat to maintain a particular floor temperature.
