Feb 01, 2014 Hello, I am replacing an old Carrier mercury-model thermostat with a non-programmable Cool/Heat Honeywell CT31A thermostat. The old thermostat was controlling air conditioning and electric heating through five connectors labeled Y, G, W, R and a mysterious A (although near the unconnected 4 and WITHOUT any jumper between them).

PROGRAMMED OPERATION

Introduction

The Base Series Programmable Thermostat provides four periods

per day (MORNING, DAY, EVE, NIGHT) and two schedules per
week (MoTuWeThFr and SaSu). A separate time, heat setpoint,

and cool setpoint can be set for each period and schedule. Before

starting to actually program the thermostat, fill out Table 1 with the
values you wish to program. (The Energy Starr, US Department of

Energy recommended time and temperature values are already
programmed for you as a starting point and are shown on the left

side of the table.)
The first press of the PROGRAM button brings up the

programming mode and places you at morning of the current day
