5 Section 1 Uponor Climate Cŏntrol Network System Thermostat Overview The Uponor Climate Cŏntrol Network System Thermostat is designed specifically to function within the network control system. The thermostat is available in two models vertical and horizontal and displays air, slab, humidity and outdoor temperatures. The thermostat controls two stages of heat, two stages of cooling and supplemental heat all via a single pair of thermostat wires (18-22 AWG). The user can change the display, modes, temperature setpoint, humidity setpoint, fan and heat recovery ventilator (HRV) from any thermostat in the control system. The thermostat also offers an optional feature called master passing. This is an optional feature that changes HVAC control of a room to the current thermostat being manually adjusted. This manual provides standard installation and operation procedures for the thermostat. A list of terms commonly used in this manual is provided below. Getting Ready Check the contents of the thermostat package (see Table 1-1). If any of the contents are missing or damaged, contact your Uponor sales representative or distributor for assistance. Term Draft barrier DZCM HRV HVAC Master passing PEX Setpoint Slab Temperature Offset Zone Thermostat Style Surface Mount (A ) Flush Mount Vertical (A ) Flush Mount Horizontal (A ) Definition A material that blocks or is intended to block air passage Digital Zone Control Module Abbreviation for heating recovery ventilator Heating, ventilation and air conditioning An optional feature that changes HVAC control of a room to the current thermostat being manually adjusted Abbreviation for crosslinked polyethylene. This refers to the desired thermostat setting. The room setpoint temperature is the target temperature for the room. This refers to a concrete slab under which radiant heating has been installed.

7 Section 2 Installation Methods Mounting the Thermostat Install the thermostat on an interior wall of the desired zone, approximately 5 feet (1.5 meters) above the floor. Do not mount the thermostat in a location that may be affected by heat sources or cold drafts. If necessary, install a draft barrier behind the control to prevent air from blowing through the wiring hole and affecting the control s built-in sensor. Avoid mounting the thermostat in the following locations: Near or around windows On outside walls Near fireplaces In the corner of a room Behind doors Near dimming switches On interior walls susceptible to solar gains Near stoves, lamps, televisions, computer monitors, etc. In damp or humid areas Surface Mount The following steps outline how to mount the surface-mount thermostat. 1. Locate an area to mount the thermostat. 2. Place case back on the wall and mark areas for the screw and connector holes with a pencil. Figure 2-1: Case back of thermostat being mounted on wall 3. Insert drywall anchors into the wall at the marked locations and cut out a hole in the wall to receive the main connector. Figure 2-2: Inserting drywall anchors 4. Using appropriate screws (not included), attach the case back to the drywall anchors. 5. Wire the thermostat. Refer to Section 2: Wiring the Thermostat and Section 4: Wiring Diagram. Figure 2-4: Wiring thermostat procedure 6. Use the supplied #4 screws to mount the thermostat into the case back. Figure 2-5: Mount thermostat procedure 7. Snap the case front into place on the case back. Figure 2-3: Case back of thermostat procedure Figure 2-6: Mount thermostat procedure Uponor Climate Cŏntrol Network System Thermostat Installation and Operation Guide 7

8 Flush Mount The following steps outline how to mount the flush-mount thermostat. 4. Wire the thermostat. Refer to Section 2: Wiring the Thermostat and Section 4: Wiring Diagram. Note: The flush-mount thermostat is designed for mounting in ½inch drywall. 1. Loosely attach the wings into the back of the thermostat with the supplied hardware as shown in Figure 2-7. (Only tighten the screws one or two turns into the wings.) Figure 2-11: Flush mount thermostat Figure 2-9: Flush mount thermostat Figure 2-7: Flush mount thermostat 5. Push in any insulation and cut away any excess drywall or paper to ensure nothing interferes with the action on the wings. The thermostat will not mount correctly if there is any interference. 6. Place the thermostat in the hole in the drywall and hold it tight against the wall. Figure 2-12: Flush mount thermostat 8. Snap the flush-mount thermostat skin into place on the thermostat. 2. Use the template provided to mark the cutout in the drywall for the thermostat. Use a level to ensure the cutout is straight. 3. Cut around your marking with a drywall saw or utility knife. Figure 2-10: Flush mount thermostat Figure 2-8: Flush mount thermostat 8 7. Turn the wing screws slowly. Initially, the wings will turn 90 degrees behind the drywall. As you continue tightening, they will secure the thermostat in place. Figure 2-13: Flush mount thermostat Important: Do not overly tighten the wings.

9 Wiring the Thermostat Wiring the Slab Sensor Connect the two wires from the sensor to the slab sensor terminals on the thermostat as shown in Figure In this case, polarity does not matter. The following steps outline how to wire the thermostat. Note: All wiring must comply with local electrical codes and specifications. Uponor recommends 18 AWG LVT or similar wire for all thermostat connections. Strip all wires to ¼ (6.3 mm) to ensure proper connection to thermostat terminal blocks. If an optional sensor is used (e.g., a slab sensor), run a single-pair, 18 AWG wire from the sensor to the control. Tools Required Small, flat-head screwdriver Phillips screwdriver Wire cutter and stripper Caution: To prevent damage to the thermostat, do not connect it to 24-volt control systems or devices other than the Digital Zone Control Module (DZCM). Power and Data Wiring 1. Refer to the DZCM Installation Guide for wiring to the DZCM. 2. Run a single-pair, 18 AWG LVT wire from the DZCM to the thermostat. 3. Attach the wires to the Pwr/ Comm terminals shown in Figure Note: Be sure to observe the thermostat s polarity and wire color. Use the red wire to connect the positive terminal on the thermostat to the positive terminal on the controller. Figure 2-14 Power and data wiring Placing the Slab Sensor The following steps outline how to install a slab sensor. Figure 2-15 Wiring the slab sensor 1. Place the slab sensor between two PEX tubes in the floor. 2. If the floor is wood construction, place the sensor as close to the floor surface as possible. If the floor is concrete or like construction, place the sensor no deeper than the mid-point of the slab. 3. Uponor recommends placing the sensor wire in a conduit for easy replacement. Ensure the sensor is in direct contact with the floor material (wood, concrete, gypcrete, etc.). Uponor Climate Co ntrol Network System Thermostat Installation and Operation Guide 9
