Warmup WSC – 1021 Terra WiFi Thermostat
Pack Contents
Safety Information
- The thermostat must be installed by a qualified electrician. It requires a permanent 110V – 240V AC, 60Hz supply. The thermostat contains a Class A GFCI with a 5mA trip level and the wiring must conform to the local electrical code.
- Isolate the thermostat from the main supply throughout the installation process.
- Install the thermostat in an area with good ventilation. It should not be beside a window/door, in direct sunlight or above another heat-generating device (e.g. radiator or TV).
- Ensure the distance from your router to the thermostat is not excessive. This will ensure the wireless connection is not subject to range or interference issues once installed.
- Conduits are only required where it is mandated by state or provincial code. Please refer to the local electrical code for compliant applications.
- The thermostat and its packaging are not toys; do not allow children to play with them. Small components and packaging present a risk of choking or suffocation.
- The thermostat is suitable for indoor use only. It must not be exposed to moisture, vibrations, mechanical loads or temperatures outside of its rated values.
- For safety and licensing reasons, unauthorized change and/or modification of the thermostat is not permitted.
Step 1 – Installation
- Isolate the thermostat supply from the main supply.
- Unclip the display from the power base.
- Install a 3-1/2” (89 mm) deep single gang or 2-gang box with mud ring in your preferred thermostat location. Pull wires (heater, supply and sensor) through the gang box and complete terminal wiring.
Step 2 – Wiring Connections
WARNING!
The thermostat must be installed by a qualified electrician in accordance with National Electrical Code.

Welcome to the Terra thermostat
How to quickly change the temperature
- Press
/
to change your target temperature.
- If in program mode this will set a temporary override until your next heating period. See “How to set a temporary override”.
- If in manual mode this will set a fixed target temperature. See “How to set into Manual Mode”
- Once the target temperature is set above the current floor/air temperature the heating indicator will appear in the top right-hand corner.
How to quickly change mode
Mode select allows you to quickly change from manual mode to program mode or simply switch the heating off.
Heating
How to set up a program
Setting a program allows you to set comfort temperatures at set times throughout the day. Days can be programmed individually, all days the same or weekdays as a block and weekends as a block, the choice is yours.
How to set into Manual Mode
Setting into manual mode allows you to set a fixed target temperature for the thermostat to achieve. The thermostat will continue to maintain this temperature until another operating mode or temperature is selected.
How to set a Temporary Override
Setting a temporary override allows you to set a target temperature that will override your current heating program until your next heating period or for a set duration.
Energy Monitor
How Energy Monitor works
The thermostat learns how you use your system and how your house reacts to heating and weather. Using the MyHeating App, energy monitoring will show the amount of energy consumed over a certain time period. This will be calculated through system power multiplied by efficiency and run time. You will need to enter the power of your system, and in some cases, the efficiency. If you do not know these, speak to your installer or system manufacturer.
SmartGeo
How SmartGeo works
SmartGeo is a unique technology developed by Warmup and built into the MyHeating App that uses an advanced algorithm to understand the most efficient heat settings for your home. Working automatically; it learns your routines and location through background communication with your smartphone and lowers temperatures when you are away, only rising them up to your ideal comfort temperature in time for your arrival home. Smartgeo will operate when the thermostat is in the program or manual run modes. It is turned off by default. Use the MyHeating App to switch SmartGeo on.

Troubleshooting
![]() |
Control (5 & 6) / Internal Air sensor error | 1. Please see Table 1.0 and ensure you have selected the correct thermostat application. 2. (Electrician Required) Electrician is required to verify that the floor sensor has been wired correctly. If it is correctly wired the electrician will need to check the resistance of the floor sensor using a multi-meter. For temperatures between 68°F – 86°F the resistance of the floor sensor should measure between 8K ohms and 12K ohms. If the electrician finds a fault, and the thermostat is in the room to be heated then it can be set into “Air Mode”. To set into “Air Mode”, see Table 1.0 Thermostat application. If “—” still remains when set into air mode the thermostat will have to be replaced. |

Limit Sensor Error (6 & 7) | |
The heating is coming on earlier than the programmed times | Adaptive learning (Early start) On | Adaptive learning (Early start) will use the historic heating/cooling rates for the time of day, historic external temperatures and the forecast external temperatures, to work out the heating start time in order to reach the comfort time at the start of the comfort period. It will only work in Program Mode. |
WiFi Error Symbol

WiFi not set up | 1. Download and open the MyHeating App
2. Remove the thermostat from the wall 3. Scan the QR code on the back of the display 4. Place thermostat back on the wall and power-up 5. Thermostat will be in pairing mode for 1 minute. App should automatically connect to the phone 6. Follow instructions in App |
WiFi disconnected | Follow the step above to try and to reconnect to the WiFi Network.
If the thermostat still fails to connect, see WiFi Troubleshooting. |
Clock Icon![]() |
Time and Date not set | Connect the thermostat to a WiFi network or alternatively set the time and date from the settings menu. |
GFCI![]() GFCI |
GFCI test button | The GFCI feature is used to detect any leakage of current from your heating system. During a ground fault the two lines of the load will be cut off. Once your thermostat is installed and connected to a
power supply you can test the GFCI function by increasing the set temperature until heating is on – the heat up icon ( ) will be illuminated – and pressing the “TEST” button.
If your test is successful you will see the GFCI error icon and you will need to hold “X” for 3 seconds in order to restore heating operation. |
Heater error | The GFCI has tripped due to a fault in the heater.
(Electrician Required) Electrician required to verify that the heater has been wired correctly. If correctly wired please conduct a resistance test and insulation resistance test on the heater to see if damage has occurred. |

Relay icon![]()
|
Relay error | The thermostat has detected that one of the relays has FAILED.
