Thermal Controlled Relay Module

How to Setup:

Setting the parameters(P0, P1, P2, P3, P4, P5, P6)

The module has seven parameters to set, which makes the module flexible for different applications. Setting a parameter on the module is done using the switches on the module only. To set any parameter, long-press the SET button for around 5 seconds. After 5 seconds, the module displays P0, the ‘+’ and ‘-” buttons can be used to scroll through the different parameters(P0 to P6). Once you decide which parameter to be changed, go to that parameter using ‘+’ and ‘-” buttons and press the set button once. Once you are in the specific parameter, you can change the values using the ‘+’ and ‘-” buttons. After no activity for 5 seconds, the values will be set automatically and the module will return displaying its default temperature.

The table in the next section depicts the range of the parameters and the usual values for the proper functioning of the module.

1. Heating or Cooling Parameter (P0):

The first parameter P0 has two settings, Cooling or Heating. It can be set based upon the application in which it has to be used(i.e. For heaters/coolers). While connecting a cooling system, set the P0 to ‘C’, as the relay will energize when the temperature is reached. Whereas, when using a heating system, set the P0 to ‘H’, as the relay will de-energize when the set temperature is reached.

2. Backlash/Hysteresis Parameter (P1):

This parameter can be used to prevent continual triggers whenever the temperature is around the set temperature. Or to say, the desired change in the temperature before relay actuation. If P1 is set to the default value of 2 Degrees C and the trigger temperature is 30 Degree C, the relay will only de-energize once it reaches around 28 Degrees C and not 30 Degree C.

3. Upper limit of the thermostat module (P2):

This parameter can be used as a safety measure. It sets up an upper limit for the user to set the high-temperature trigger value.

4. Lower limit of the thermostat module (P3):

This parameter can be used as a safety measure. It sets up a lower limit for the user to set the low-temperature trigger value.

5. Temperature Offset Correction Parameter (P4):

You can set an offset value if the temperature sensor is unable to display the exact value as the real temperature. If there is a difference in the displayed data and the actual data, an offset value can be set from a range of -7 to 7.

6. Trigger Delay Parameter (P5):

The P5 parameter can be used to provide a delay in relay actuation when the trigger temperature has been achieved. The delay in this parameter can be set up to 10 minutes.

7. Temperature Alarm Parameter (P6):

The parameter P6 is used as a safety feature. The relay switches off when the value set is reached. The on board display also shows a ‘---’ to indicate an alarming condition. It can be set to ‘OFF’ as default.

Setting the parameters of the Temperature Control Switch

To set the different parameters of the module, long press the ‘Set’ button on the module and change the values using the ‘+’ and ‘-’ buttons.

Settings Parameter Range Default Value
H/C P0 H/C Heat/Cool Mode
Hysteresis Set P1 0.1 ~ 15 2
Upper Limit P2 110 110
Lower Limit P3 -50 -50
Correction P4 -7.0 ~ 7.0 0
Delay Start Time P5 0-10 Mins 0
High Temp Alarm P6 0-100 OFF

Note: Long pressing the +/- button will reset the values to default.

We will not take back merchandise that is not in original packaging, serialized items not matching the serial number on the receipt, missing instruction manuals or accessories, excessively worn packaging, abused, damaged from incorrect use, dented, or marred. Keep in mind that we need to be able to resell the item that is returned so keep this question in mind: “if you were buying this product, would you buy one in the condition of the product you are returning?”. We reserve the right to charge up to a 25% restocking fee for returned merchandise, we will contact you upon receipt of your returned goods if we feel a restocking fee is necessary. Most items that returned in new condition within the 30 day return period will not be subject to a restocking fee.

Final Sales

Certain items are not eligible for returns due to the nature of the products: Batteries, Tools, Test Equipment, Semi-Conductors, Capacitors, Cut-to-Order Items, & Chemicals.

Special Orders: Some special order items are final* depending on the product itself or the manufacturer’s return policy. If you want to return a special order, we can check with the manufacturer to see if it can be returned and if they charge a restocking fee. Please note that the manufacturers restocking fee is at their discretion and may exceed 25%.

Defective Items

In the unfortunate event that you receive an item that is defective, please contact us by email or phone as soon as possible so that we can help resolve the problem. Defective items will generally need to be returned to us for evaluation and then we will have a new replacement sent to you. If you need an advanced replacement, we would need to charge you for the new product upon shipping and provide a refund when the defective product is returned. For items purchased more than 90 days ago, you will typically need to contact the manufacturer for warranty directly. Depending on the type of sale, we may still retain a record of your receipt - if this is the case we can print a new copy for the warranty claim.
