Honeywell Home RLV4300 Programmable Thermostat 

Display

The thermostat normally displays the actual (measured) temperature. To view the set temperature (setpoint), press either of the buttons once.

Description

The RLV4300 thermostat can be used to control an electric heating system such as a baseboard heater, a radiant floor, a radiant ceiling, a convector, a fan-forced heater, etc. The thermostat cannot be used
with the following:

• a resistive load under 2 A
• a resistive load over 12.5 A
• systems are driven by a contactor or a relay (inductive load)
• central heating systems

SUPPLIED PARTS

• One (1) thermostat
• Two (2) 6-32 mounting screws
• Two (2) solderless connectors

Installation

TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK.
Loosen the screw underneath the thermostat and separate the front plate from the back plate

NOTE: The screw cannot be completely removed.

Connect the thermostat wires to the power and to the load using solderless connectors for copper wires. The thermostat wires are not polarized; meaning either wire can be connected to the load or to the power supply.

NOTE: All cables and connections must comply with local electrical codes. This thermostat has tinned copper wires for line and load connections. Special CO/ALR solderless connectors must be used if these wires will be connected to aluminum conductors.

 

Mount the back plate to the electrical box using the provided screws. Insert the screws through a pair (left or right) of mounting holes on the back plate.

Re-install the front plate of the thermostat onto the back plate and secure it with the screw underneath the thermostat.

NOTE: If there is a protective film or sticker on the thermostat’s screen, peel it off. Apply power to the heating system. Verify the installation by checking that the heater can be turned On and Off by raising and lowering the setpoint using the buttons.

ATTENTION: Keep the thermostat’s air vents clean and free from obstructions at all times.

3. Press the button to exit.

Temperature Display and Setting

The thermostat normally displays the room (measured) temperature.

• To view the set temperature (setpoint), press once on either button.
• To change the setpoint, press one of the buttons until the desired setpoint is displayed.
• The screen is backlit for 10 seconds when any button is pressed.

Modes of Operation

The thermostat has 3 modes of operation:

Automatic (programmable) Mode
To use the Automatic mode, press the button until AUTO is selected (outlined) on the screen. The current period number will appear. In this mode, the thermostat automatically adjusts its temperature setpoint according to the period of the day (wake up, leave for work, return home, and sleep). You can program up to 4 periods in a day. You can set up 2 different programs: one for the weekdays (Monday to Friday) and another one for the weekend (Saturday and Sunday).

The thermostat is pre-programmed with the following schedule:

Period		Monday to Friday		Saturday & Sunday
		Start Time	Temperature	Start Time	Temperature
1	Wake	6:00	21°C (70°F)	6:00	21°C (70°F)
2	Leave	8:00	16°C (62°F)	—	—
3	Return	18:00	21°C (70°F)	—	—
4	Sleep	22:00	16°C (62°F)	22:00	16°C (62°F)

To temporarily override the current setpoint, set the desired temperature using the buttons. The new setpoint will be used until the beginning of the next period.

To modify the schedule

1. Press the button until AUTO is selected.
2. Press the button.

Each time you press the button, the thermostat displays one of the periods in the following order (from left to right):

Monday to Friday				Saturday and Sunday
MO TU WE TH FR				SA SU
1	2	3	4	1	2	3	4

Set the start time for the period using the and buttons.

NOTE: To disactivate the period, press the button. Instead of displaying the start time of the period, the thermostat will display During operation, the thermostat will skip over that
period.

• Set the temperature for the period using the buttons.
• Repeat steps 2 to 4 for the remaining periods.
• Press the button to return the thermostat to a normal display.

Manual (hold) Mode
To use this mode, press the button until MAN is selected (outlined) on the screen. Then, set the desired temperature using the buttons. In this mode, any modification to the temperature setpoint must be done manually.

Economy Mode

To use the economy mode, press the button until  ECONO is selected (outlined) on the screen. This mode is ideal for weekend residences as it can be used as follows: The temperature is kept at an economy level during most of your absence and is raised to a comfortable level by your usual arrival. If you do not show up, the temperature returns to the economic level until next weekend.

The economy mode has two periods which should be set as follows

Period	Temperature Setting	Start Time Setting
1	Set to a comfortable level.	Set a time where the temperature starts to rise to reach a comforta- ble level by the time you arrive.
2	Set to an economy level.	Set a time where the temperature starts to drop to an economy level if you do not show up.

The economy mode should be used as follows:

• Place the thermostat in economy mode during your absence.
• When you arrive, place the thermostat in automatic mode or in manual mode before the temperature drops back to the economic level.
• When you leave, switch the thermostat back to economy mode.

To program the two periods of the economy mode

1. Press the button until ECONO is selected.
2. Press the button. Period 1 is displayed.
3. Set the start day for the period using the button.
4. Set the start time using the and buttons.
5. Set the temperature for the period using the buttons.
6. Press to select period 2.
7. Repeat steps 3 to 5 to set the day, time, and temperature for period 2.
8. Press to return the thermostat to a normal display.

Thermostat Reset

Warning: When the thermostat is reset, all parameters (clock, configuration, and schedules) return to their default settings. If necessary, reprogram them.

• Press and hold the button.
• Insert a pointed object (e.g., paperclip) through the reset opening. Remove it when the thermostat’s screen becomes blank.
• Wait one second and release the button.

Power Outage
During a power outage, the thermostat display remains lit for approximately the first 15 minutes during which the LP (low power) indicator appears. The settings are saved in memory. However, if the power failure exceeds 5 hours, only the thermostat’s clock must be re-adjusted. When power returns, the thermostat returns to the mode of operation preceding the power outage

Troubleshooting

PROBLEM	SOLUTIONS
Thermostat is hot.	This is normal. Under normal opera- tion, the thermostat housing can reach a temperature between 35°C (95°F) and 40°C (104°F).
	Correct if any the following conditions applies:
Displayed temperature is wrong.	•           The thermostat is exposed to air draft. •           The sticker on the thermostat’s screen has not been removed.
	•           The thermostat is located near or above a heat source such as a light dimmer.
Wrong time is dis- played.	The thermostat was probably without power for more than 5 hours.
Temperature does not change according to the programmed schedule.	Check that the thermostat is in auto- matic mode. Check the schedule and clock settings.
Display disappears and reappears after a few minutes.	The thermal protection device on the heater was temporarily opened. This can happen if the heater is obstructed by furniture or curtain and has over-heated, or if the heater’s thermal protection device is too sensitive.
