Press the Fan button to cycle to the next available Fan mode.

Fan will still operate if fan is set to On.

Off: Heating and cooling system is off.

Em Heat (TH4210U only) (only for heat pumps with auxiliary heat): Thermostat controls Auxiliary Heat.

Cool: Thermostat controls only the cooling system.

Heat: Thermostat controls only the heating system.

Auto: Thermostat selects heating or cooling as needed.

NOTE: Available System modes vary by model and system settings.

Cycle through the modes until the required System mode is displayed and leave it to activate.

Press the Mode button to cycle to the next available System mode.

Turn the power on at the breaker box or switch.

Align the UWP with the thermostat, and push gently until the thermostat snaps in place.

Push excess wire back into the wall opening.

In Installer Setup, set changeover valve to O (for cool changeover) or B (for heat changeover).

In ISU set Heat system type to Radiant Heat.

Move R-Slider Tab on UWP to the R setting.

Provide disconnect means and overload protection as required. NOTES: Wire specifications: Use 18- to 22-gauge thermostat wire. W Do not use this terminal for heat pump applications! Heat-only System (power open zone valve) Wiring conventional systems: forced air and hydronics The most commonly used terminals are shaded. Note: Not all terminals may be used, depending on the system type that is being wired. See THP9045 instructions for more information. Use the K terminal in place of the Y and G terminals on conventional or heat pump systems to provide control of the fan and the compressor through a single wire-the unused wire then becomes your common wire. The THP9045A1098 C-wire adaptor is used on heat/cool systems when you only have four wires at the thermostat, and you need a fifth wire for a common wire.

NOTE: Slider Tabs for U terminals should be left in place for T4 Pro models. If there is one wire connected to the R terminal and one wire connected to the Rc terminal, set the slider to the down position (2 wires).If there is only one R wire, and it is connected to the R, Rc, or RH terminal, set the slider to the up position (1 wire).Use built-in jumper (R Slider Tab) to differentiate between one or two transformer systems.Insert and tighten mounting screws supplied with the UWP. Pull the door open and insert the wires through wiring hole of the UWP.If your box contains yellow anchors, drill 3/16вЂќ holes.If your box contains red anchors, drill 7/32вЂќ holes.See Figure 2.Дrill holes at marked positions, and then lightly tap supplied wall anchors into the wall using a hammer. Before starting, turn the power off at the breaker box or switch.
