Question: Replacing a round Honeywell T87 with a Digital Honeywell Thermostat Hello - I am replacing a round Honeywell thermostat with a non-programmable digital Honeywell unit. I have a hot water system with multiple zones and with no air conditioning. There are three wires at the thermostat. On the old round unit the red wire went to the R terminal, the white wire went to the w terminal and a green wire went to B terminal.
I hooked up the new stat the same way but it would not work. If I selected 'fan on' instead of 'fan auto' the zone would heat up but would not shut off (hot water kept flowing even if I selected a temp below room temp). Appreciate your help.
Patrick - 1/20/12 Reply: Patrick, typically the three wire thermostat hookups would be exactly the same for the old and new thermostats. For details of wiring a typical and simple digital Honeywell thermostat, see.
For help in understanding the wiring of your old thermostat, see and also see Question: Replacing a mercury thermostat with a digital unit I am replacing an old mercury thermostat with a digital. My system is a heat pump.
My neighbor gave me the digital, no instructions, no box. I'm trying to decide if this is even a heat pump compatible thermostat. On the therm it has c, g, rc, rh (which are linked by a black wire.) w, y, b, and o. Coming out of my wall is, white connected on old therm w2, yellow connected to y, green conn g, black conn e, red to r, blue to b and bro to x. Any help would be great. Kurt 6/4/12 Reply: Kurt, as you see in the examples at For help in understanding the wiring of your old thermostat, see and also see. Many thermostat wiring setups are straightforward or 'cookbook' but why not find the brand name on your thermostat and then you can obtain the installation instructions right from the manufacturer?
Also, Honeywell's thermostat replacement advice (and most likely that of all thermostat manufacturers) warns: Watch out: MERCURY NOTICE: Do not put your old thermostat in the trash if it contains mercury in a sealed tube. Contact your local waste management authority for instructions regarding recycling and proper disposal.

Areas in the direct airstream of air diffusers. Pre-Installation Maximum Wire Lengths Thermostat to HVAC Equipment The thermostat may not function properly if the total resistance of any of the thermostat to HVAC equipment wires exceeds 2.5 ohms.To ensure that wire length does not cause excess resistance, refer to Table 1 and ensure that the wires from the thermostat to the HVAC equipment are not too long. Installation This section provides installation instructions.
Before you begin, read through the pre-installation information, beginning on 9, and also verify the following conditions are met:. A wire access hole is available at the thermostat location. The wires are accessible through the hole. To wire the thermostat: 1. Connect the wires to the terminal block(s) packaged in the box with the thermostat. (The programmable thermostat has two terminal blocks, the non-programmable thermostats have only one):.
Remove approximately 1/4 inch (6 mm) of insulation from the wires. Installation 2. Align the pins on the circuit board with the holes on the bottom of the terminal blocks and gently push the wired terminal blocks into place on the circuit board. See Figure Figure 5.

Space unoccupied indicator. No programming/ Timed override indicator scheduling-related buttons appear. Space occupied indicator Button lock indicator Overview of Operation If configured properly, both programmable and non-programmable thermostats will control HVAC equipment to maintain room temperature automatically. Operation Non-Programmable Thermostats Non-programmable thermostats do not have timekeeping or scheduling capabilities.They will continue to maintain heating and/or cooling setpoints until an operator makes changes to the setup.Therefore, only the following tasks may be required performed:.
Change the system mode. 5 sec to save and exit. Programmable Thermostats Programmable thermostats contain all of the functionality of the non-programmable thermostats, but they also keep track of the date, day of week, and time of day for scheduling purposes. Programming This section describes how to program the thermostat after it has been installed and configured. Operation Scheduling The thermostat can be configured for two periods (day and night) or four periods (morning, day, evening, and night).The chosen number of periods are applied to each day of the week when you program the thermostat. Each period can have a unique start time, heat setpoint, cool setpoint, and fan setting. Operation Table 9.

Operation To set the schedule: 1. Press.The display shows only the following elements: Mo Tu We Th Fr Sa Su 2.
Press Note: At this point the thermostat is in schedule change mode. It returns to normal operating mode if no buttons are pressed for 45 sec.To manually exit schedule change mode, press and hold for 2 sec. Operation Day-to-Day Operation After a programmable thermostat is configured and the schedule is programmed, the thermostat automatically changes the setpoints and fan settings according to the schedule.However, there are some operator tasks that you may need or want to perform:. Operation Timed Override (TOV) Mode During normal operation, the thermostat controls the HVAC equipment according to the schedule that is programmed into it.To permanently change the temperature setpoint or fan setting, make the change in the programmed schedule (see “Scheduling, ” p. Operational and Programming Reference Information This section provides additional information that may be useful for understanding thermostat operation or programming. Deadband The thermostat automatically maintains a temperature deadband between the heating setpoint and the cooling setpoint whenever automatic changeover (heat-to-cool or cool-to-heat mode) is enabled.The temperature range of the deadband is 2–9 °F (1.0–4.5°C) and is specified in the installation configuration options (see “Configuration, ”.
Note: You can manually revert to default settings by setting the appropriate installation parameter (#300 for programmable thermostats or #18 for non-programmable thermostats) to a value of 1, and exiting configuration mode. Troubleshooting This section describes troubleshooting for the thermostat.
Error Codes An error code indicates that technical assistance may be required. Try cycling the power to the thermostat as a first method to clear the error. See Table 10 below and Table 12, p.
