INSTALLATION
!WARNING
Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code.
Remove Old Thermostat
A standard heat/cool thermostat consists of three basic parts:
1.The cover, which may be either a snap-on or hinge type.
2.The base, which is removed by loosening all captive screws.
3.The switching subbase, which is removed by unscrewing the mounting screws that hold it on the wall or adapter plate. Before removing wires from old thermostat, label each wire with the terminal designation from which it was attached. Disconnect the wires from the old thermostat one at a time. Do not let wires fall back into the wall.
Batteries
2 "AA" alkaline batteries are included in the thermostat. To install the batteries, pull the battery door as shown by the arrow and lift open. Using the polarity indicated inside the battery door, insert the batteries. To close the battery door, swing the door down while pulling in the direction of arrow. Once fully down, snap the door back into position.
To replace the batteries, set system to OFF, following the instructions above.
Figure 1 – Battery door shown open
“AA” Alkaline Batteries |
Installing New Thermostat
1.Pull the thermostat body off the thermostat base. Forcing or prying on the thermostat will cause damage to the unit.
2.Place base over hole in wall and mark mounting hole locations on wall using base as a template.
3.Move base out of the way. Drill mounting holes. If you are using existing mounting holes and the holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure the base.
4.Fasten base snugly to wall using mounting holes shown in Figure 2 and two mounting screws. Leveling is for appearance only and will not affect thermostat operation.
5.Connect wires to terminal block on base.
6.Push excess wire into wall and plug hole with a fi re resistant material (such as fi berglass insulation) to prevent drafts from affecting thermostat operation.
7.Carefully line the thermostat up with the base and snap into place.
Thermostat can be powered by system AC power or Battery. If
is displayed, the thermostat is battery powered. If
is not displayed, thermostat is system powered with optional battery back-up. When battery power remaining is approximately half, the
will be displayed. When "Cambiar 
" is displayed, install fresh “AA” alkaline batteries immediately. For best results, replace all batteries with a premium brand alkaline battery such as Duracell® or Energizer®. We recommend replacing batteries every 2 years. If the home is going to be unoccupied for an extended
period (over 3 months) and
is displayed, the batteries should be replaced before leaving. When less than two months of battery life remain, the setpoint temperature will offset by 10 degrees (10 degrees cooler in Frio mode / 10 degrees warmer in Frio mode). If offset occurs, the normal setpoint can be manually reset with 
or 
. Another offset will occur within two days if batteries are not replaced.
SS/HP Switch
(Conventional or Heat Pump Selection)
The SS/HP switch is factory set to the SS position. In this position, thermostat is confi gured as conventional single stage. If you have a single stage heat pump system, switch SS/HP to HP position (see fi gure 2).
Gas/Elec Switch (Fan Option)
The GAS/ELEC switch is factory set to the GAS position. In this position, the thermostat will not power the circulator fan on a call for heat, but will power the circulator on a call for cool.
If your system requires that the thermostat power the circulator fan on a call for heat, this switch should be set to the ELEC position. Typically, gas and oil heating systems do not require the thermostat to power the circulator fan during a call for heat. If your heat is gas or oil, the switch should be set to the GAS position.
When the thermostat is confi gured for Heat Pump, the thermostat will always power the circulator fan on a call for heat in the HEAT mode.
