1. For the thermostat guard,
refer to G Series Thermostat and Humidistat Guards.
2. Can also be used where one unit
provides both heating and cooling by adding a jumper between terminals 2 and 3.
3. Includes a horizontal
faceplate for horizontal mounting. The plate is for on-the-job
installation over a vertical plate. Can field-convert to other
configurations. The T26S-18 is a universal replacement for Honeywell
T451A, -B; White Rodgers 179-1, 180-1, 181-1, 182-101, -102; Robertshaw TA500,
TH71, -72, -79, -500, TX550. T26T-3 replaces Honeywell T4051A, -B, T6051A;
White Rodgers 151-6, 152-9, 159-3, -5.
