Frequently Asked Questions - Tempra Trend STIEBEL ELTRON

Is the Tempra Trend suitable as a kettle?

Although categorized as a kettle, the Tempra Trend is a tankless water heater designed to provide continuous hot water for domestic use. It is not a traditional kettle for boiling water.

What is the required electrical power?

The power depends on the model: from 9 kW (208 V) to 36 kW (240 V). Check the product label and make sure your electrical installation can support the load. Some models require multiple circuits.

How to adjust the water temperature?

Use the rotary knob on the front panel. Turn clockwise to increase, counterclockwise to decrease. The temperature can be set from 20 °C to 60 °C. An off mode is accessible by turning fully counterclockwise.

What to do if the water is not hot enough?

Check that the water flow is not too high and that the supply voltage is correct. Clean the strainer filter to remove blockages. If the problem persists, the safety thermal switch may have tripped.

How to reset the safety thermal switch?

First turn off the power supply at the circuit breaker. Open the front cover, locate the reset buttons on the heating elements, and press them until you hear a click. If tripping is frequent, contact technical support.

What is the maximum allowed water pressure?

The maximum pressure is 1.0 MPa (150 psi). If the supply pressure exceeds this value, install a pressure reducer upstream of the device.

Is a pressure/temperature relief valve required?

No, it is not necessary for a tankless water heater like the Tempra. However, if local code requires it, a valve can be installed on the hot water outlet.

How to clean the device?

Regularly clean the strainer filter located at the cold water inlet. Descale the heating elements if necessary with a descaling solution. Also check water quality to prevent scaling.

What to do if an error code appears on the screen?

The Tempra Trend does not display error codes (unlike the Tempra Plus). If an electrical problem occurs, the device may not heat. Contact Stiebel Eltron technical support at 800-582-8423.

Can the device be installed outdoors?

No, the Tempra Trend must be installed in a frost-free location. It should not be exposed to temperatures below 2 °C (36 °F) to avoid damage. Always install indoors.

4. General

The Tempra Trend and Tempra Plus units are designed to supply hot water for a house, apartment or certain commercial applications. Unlike a conventional storage type water heater, the Tempra tankless water heater does not store hot water. Instead, water is heated instantaneously as it flows through the unit. The Tempra offers greater energy efficiency than storage type water heaters due to the absence of stand-by losses and reduced hot water pipe runs.

The input of heat into the water is controlled electronically. The Tempra will deliver any water temperature between 68 °F (20 °C) and 140 °F (60 °C). Set the desired temperature using the knob on the front cover. The Tempra Trend and Tempra Plus temperature adjustment knob can be set to: OFF, 68–140 °F (20–60 °C). The maximum temperature is electronically limited to 140 °F (60 °C).

For reasons of appliance efficiency and durability (scaling), the optimum temperature setting lies between 86 °F (30 °C) and 120 °F (50 °C).

The Tempra has a built-in display that allows for user customization and information feedback.

8. Water connections

NOTICE: Excessive heat from soldering on copper pipes near the Tempra may cause damage. The cold water connection to the unit must be disconnected periodically in order to clean the filter screen. It is required to use water connections that are easily detachable such as braided steel flex connectors.

NOTICE: Hard water or water with a high mineral count may damage the unit. Damage to the unit caused by scale or a high mineral count is not covered under the warranty.

▶ All plumbing work must comply with national and applicable state and local plumbing codes.
▶ A pressure reducing valve must be installed if the cold water supply pressure exceeds 150 psi (10 bar).
▶ Make certain that the cold water supply line has been flushed to remove any scale and dirt.
The Tempra unit has a built in filter screen that should be cleaned from time to time. Clean screen and put the screen and the washer back into their original position.

The cold water connection (inlet) is on the right side of the unit, and the hot water connection (outlet) is on the left side of the unit.

NOTICE: Tankless water heaters such as the Tempra are not required to be equipped with a temperature and pressure relief valve (T&P). If the local inspector will not pass the installation without a T&P, it should be installed on the hot water outlet side of the unit.

The Tempra on the hot side is designed for connection to copper tubing, PEX tubing or a braided stainless steel hose with a 3/4" NPT female tapered thread.
The plumbing on the cold water inlet side needs to be such that it can easily be removed to allow access to the inlet filter screen. The easiest way to achieve this is to us a stainless steel braided hose connector. If soldering near the unit is necessary, please direct the flame away from the housing of the unit in order to avoid damage.
▶ When all plumbing work is completed, check for leaks and take corrective action before proceeding.

9. Electrical connection

WARNING: Electrocution

Before beginning any work on the electric installation, be sure that main breaker panel switches are "Off" to avoid any danger of electric shock. All mounting and plumbing must be completed before proceeding with electrical hook-up. Where required by local, state or national electrical codes the circuits should be equipped with a "ground fault interrupter". The unit must be properly grounded in accordance with state and local codes, or in absence of such codes, in accordance with national electric code or the Canadian electric code. Failure to electrically ground the product could result in serious personal injury or death.

The Tempra should be connected to properly grounded dedicated branch circuits of proper voltage rating. Ground must be brought to the "Ground" at the circuit breaker panel.

Consult the chart below for the recommended torque amounts on the terminal block screws.

Screw Size (mm)	Min. Torque (N·cm)	Min. Torque (Lbf·in)
M6	200-250	17.7-22.1

Using the proper torque specifications to secure wire to the wiring block helps to avoid personal loss or property damage.

10. Commissioning the water heater

WARNING: Open the hot water faucet for a few minutes until water flow is continuous and all air is purged from water pipes. The unit's cover must be installed before the circuit breakers are turned on.

▶ Check that the set value transducer cable is plugged into the slot TSoll D on the main PCB. If the cable was disconnected for any reason during installation, ensure it is reconnected to slot TSoll D before supplying power to the water heater.
▶ Fill the unit up completely with water.
▶ Close the cover and fix it using the screw with the lock washer.
▶ Turn on circuit breakers to bring electrical power to the unit.
▶ Adjust the water temperature to the desired level using the knob on the front cover of the unit.
▶ Turn on hot water and wait twenty seconds until temperature has stabilized.
▶ Check the water temperature with your hand and make sure that it does not feel too hot. Reduce if necessary.
Explain to the user how the unit works and familiarize them with its use.
▶ Advise the user about possible hazards (hot water temperature up to 140 °F (60 °C)). Hand over these instructions, to be kept for future reference.

11. Normal maintenance

NOTICE: The Tempra does not contain any parts serviceable by the average user. In case of malfunction please contact a licensed plumber or electrician.

Stiebel Eltron Tempra tankless water heaters are designed for a very long service life. Actual life expectancy will vary with water quality and use. To ensure consistent water flow, it is recommended to periodically remove scale and dirt that may build up at the aerator of the faucet(s), the filter screen in the unit, or the heating canisters of the water heater.

Periodically check the water quality supplied to the water heater. Water quality can have an impact on appliance longevity and may not be covered under the manufacturer's warranty.

12. Troubleshooting

Symptom Possible cause Solution
No hot water	circuit breakers off turn circuit breakers on
	not enough flow rate to activate unit	clean filter screen at unit clean faucet aerator or shower head
	flow sensor clogged/not spinning	remove flow sensor and blow through it to make sure wheel is spinning
	water heater not plumbed correctly	ensure cold water entering on right side and hot outlet exiting on left side
Not enough hot water/restricted hot water flow	filter screen clogged clean filter scale built up on heating elements	screen at unit descale the heating elements using a descaling solution
Water not hot enough	water flow rate too high	reduce water flow rate until power light on front cover stops blinking
	voltage too low supply correct voltage to unit
	safety thermal cutout has tripped	turn off power supply, reset safety thermal cutout

If you are not able to resolve a problem please contact us toll free at 800.582.8423 before removing the unit from the wall.

Stiebel Eltron is happy to provide technical assistance. In most instances, we can resolve the problem over the phone.

12.2 Resetting the safety thermal cutout

DANGER: Electrocution

Do not attempt to reset the safety thermal cutout of this water heater unless power to the unit has been completely shut off at the circuit breakers.

The safety thermal cutout on the Tempra is designed to cut off electrical power to the heating elements if water of a too high temperature is encountered. When one of these safety cutouts have tripped, they must be reset manually.

1 OUTLET INLET

1 Thermal safety cutouts

To reset the safety cutouts, follow the following procedure:

▶ Turn off all circuit breakers attached to the water heater
▶ Open the front cover of the water heater
▶ Identify the safety thermal cutouts on the top of the copper heating canisters. The buttons at the top are the reset buttons.
▶ Press down on the buttons, take note of whether they click when pressed or not.

A heating canister that needs to be repeatedly reset may have a technical issue that should be addressed by Stiebel Eltron technical support.
